RAF Reflector Gun Sight MK.111 N, dated 1944.
The Mk III series was one of the most successful reflector sights produced during the war, it was
used in nearly every turret in RAF Bomber Command , it was also adopted by the US Navy as the Mark 9
. The rear gun turret in the picture showing the Gun Sight is on a Wellington Bomber.
Tannoy hand sets dated 1943 the one left is the handset from a 'Telephone, Loudspeaking, No 2'.
This consisted of an amplifier (control unit) and four speakers that was used by Royal Artillery
troop command posts to transmit fire orders to the guns (one speaker at each gun).
The official name of it is "Microphone, Hand, Power, No 1B' and it's catalogue number is 'YA2814'.
The one on the right, is a YA2813 which is a 'Microphone, Hand, Power, No 1A' and is listed for two
uses: 'Telephone, Loudspeaking No 3' and 'Emergency Tank Crew Control'. Thanks to Rob on the
Militaria collectors network for this information.
loudspeaker Mk.2. I have now as you can see acquired a Telephone loudspeaker Mk.2. which was
missing its Microphone, Hand, Power, No 1B' now all I need is the four loud speakers to finish the
Mine detector 4A introduced in 1944. Time to clear a lane six feet wide and 10-15 yards long averaged one minute. Interestingly the instructions are on metal tablets
.The Satchel Signals No6 is dated 1943.Unfortunately the Search Coil is a later replacement from a 4C detector but everything els is war time. Thanks to
Peter Healey for this information.
American WW11 computer true airspeed.
WW11 Oil pressure gage for a Grumman F6F Hellcat in
its original box with the original instructions and mounting screws.
The F6F Hellcat was a WW11 American Navy fighter also used by the Royal Navy.
Admiralty Pattern No 5110.E. Signaling lantern in a Admiralty Pattern box No 8979.A. Dated 1944.
Telephone attachment headgear A.A. MK.111. In the box are two breast transmitters dated 1939 and 1940 plus one set off earphones also dated 1940. The box has two holes for cables to go through and inside are three brass screw attachments I am assuming that the earphones cables go on these then a third outgoing cable goes to something els but what?
So far the general consensus seems to be that AA is likely Anti-Aircraft, and perhaps something to do with Ack-Ack plotting switchboards.The fith pictuer is actually the Royal Observer Corps as I could not find one for Ack-Ack plotting switchboards.
MK11 Astro compass and base.
All the information I have so far is that it was probably made by an American company called Sperti in WW11
and was used by the RAF as well as the American air force. I have included a picture of it being used
in a B-25 Mitchell. I am assuming that the base stays in the aircraft as they are a separate item.
Telephone set F MK.1* in its box dated 1939 fallowed by two Telephone sets F MK.11s without their boxes both dated 1941 with M.O.D arrow. Thanks to Rob on the War relics forum collectors for the following information.Telephone Set F Marks I and I*
The Telephone Set F was a portable instrument for army communication. It was not normally used forward of divisional headquarters. It provided the following facilities:
1) Calls by buzzer
2) Calls by magneto generator
3) Responds by bell to magneto generator
4) Responds by aural indication to buzzer calling
5) Speech communication
The telephone gave visual indication of a call to Switchboards UC (Universal Call) by magneto generator and buzzer, and to Switchboards F and F by magneto generator. Visual indication of a call to Switchboards Central Battery Signalling (CBS) was given by removal of the handset from the cradle.
Maximum range was 14-16 miles using D8 twisted cable or 8-10 miles using D3 cable. However, poor cable, or wet conditions tended to reduce the range, as did poor earth when using the set with an earth return. It was estimated that the effect of a poor earth could be equivalent to adding an extra 10-15 miles of cable.
It was powered by two dry ‘X’ Cells or two wet ‘S’ Cells (both types being 1.5V cells).
The set was normally carried in a wooden carrying case, which incorporated a spring stop to retain the set in it’s working position. This afforded the set some protection in bad weather if being used outside.
There were two other versions of the set. The first was the Telephone Set F Long Range, which incorporated an induction coil instead of the buzzer to increase range. The second was the Telephone Set F High Power which incorporated a valve amplifier, but could also be operated as a normal F set.
Telephone set D MK V with morse key it's all there in good condition dated 1941. Could be carried on the belt or by shoulder strap. Thanks to Rob on the Militaria collectors network for the following information.
The Telephone Set D Mk V was a portable instrument for field use in Army formations forward of divisional headquarters. It provided the following facilities:
1) Calls by buzzer
2) Responds by bell to magneto generator calling and by aural indication to buzzer calling
3) Speech communication
4) Morse communication by buzzer and key
The instrument, having a magneto bell, could only be rung by another telephone, or telephone exchange, which has a magneto generator. It could only call by buzzer, which gives visual indication to Switchboards UC (Universal Call), and aural indication to another telephone when not working through an exchange.
Maximum range was 14-16 miles (speech) and 25 miles (Morse) using D8 twisted cable or 8-10 miles (speech) and 15 miles (Morse) using D3 cable. Like the F Set, it was powered by two 1.5V ‘X’ or ‘S’ Cells.
In addition to the normal handset, the set also incorprated a single headphone, which could be used on a listening watch. The Telephone Set D Mk V* was similar but without the headphone. In army slang, the set was commonly known as a "Don Five".
Heliograph signal lamp and morse key dated 1941.
There are a few things missing off this.
The flex on the larger lamp. And the spikes used to stick the large lamp in the ground or on a tripod which I also don't have.
The tube mounted on top of the lamp has a cross hair it is for sighting in on the intended receiving station.
There are also Coloured lenses which were for night time signaling.
There is also a large compartment for the battery.

Microphone hand No 3 and and headset
which go with the Wireless Remote Control Unit E (for Wireless set No 19).
Also a small spanner set which came with them?
Thanks to Rob on the military collectors network
for all the following information and pictures of his
Wireless Remote Control Unit E and the set No 19 which explaines how it all works and goes together.
Wireless Remote Control Unit E
The WRCUE is shown unpacked in the first picture.
It has two connectors, one for the morse key socket on the set, and one with a snatch plug to attach to a Control Unit box instead of the headset.
It has full facilities of a telephone, with bell and dynamo handle for calling.
The front has, from left to right, terminals for telephone wires, control switches (will come to those later),
the ringer handle and sockets for the Microphone Hand No 3, two headphones and a relay test socket. Above the morse key is a box which controls
send-receive switching for the WS19, and a high/low modulation control switch.
The top of the unit has a plug (this is always used in the position shown,
the WRCUE is a modification of the WRCUB, where this plug was used to switch between use with Wireless Sets No 2, 3 and 9),
the telephone bell, a relay test light and a covered relay). The central picture shows a close up of the controls on the left side.
The three terminals are for connecting to telephone lines, the middle one being common. The ‘Control Line’ connects to another WRCUE,
allowing the set to be controlled from up to a mile away. The ‘Exchange Line’ connects to a telephone exchange (or a telephone such as your Tele Set D or F),
allowing the WS19 to form part of a field telephone system. When being used on the telephone exchange,
the WS19 operator has to listen in on the WRCUE and manually flick the Send-Receive switch on the modulation box.
The three control switches next to the terminals are:
Top: Switches between the Exchange and the distant WRCUE when calling the operator at either using the ringer handle.
Middle: This is a push button used to talk to the Tel Exchange operator while the Distant WRCU operator is using the WS19 morse function (i.e. W/T operation).
Bottom: The switch selects who is connected to the WS19 morse function. At ‘Normal’ it is the WRCU attached to the set, at ‘Remote W/T’ it is the distant WRCUE.
To the right of the ringer handle are the sockets for the phones and mike. The socket marked ‘Test Relay’ is used to test the function of the relay under the tombstone shaped cover above.
The plug that normally goes to the WS19 morse key socket is plugged in and the morse key is pressed. If all is functioning correctly the red light will come on
Wireless Set No 19 Basic Setup.
The pictures above show the basic 19 Set layout.
The set itself is actually three sets in one: the A Set (2 - 8 MHz), the B Set (229-241 MHz) and an Intercom system.
Originally the set was designed for use in AFVs, with the B set for tank-to-tank communication and the Intercom for the crew, although it was used in many roles including a ground station.
To allow for flexibility, the radio was controlled via various Control Unit boxes, the actual units used depending on the particular installation. My pictures show the 19 Set mounted on a carrier,
with protective grilles and a waterproof cover, with the power supply on the left of the set.
I haven't included any aerials in this picture or the aerial matching variometer.The brown lead at the top of the set is the A set aerial connector that goes to the variometer.
The B set aerial lead attached to the round connector just left of the meter.
The Control Units are connected to the set by the yellow cords,
which can be any length depending on the particular installation.
The No 2 Unit is the operator’s unit and the No 1A provides facilities for two extra users
(in a tank these would often be the commander and gunner). Further boxes could be added on for drivers etc,
but these would only operate on the intercom system. You can see that each box has a switch to enable use of the A set, B set or IC system.
The operator’s box can also be used for rebroadcast, that is, signals received on one set can be sent on another (i.e. B to A, A to B), using the N-R switch (Normal-Rebroadcast).
The last picture shows the standard early headset with Microphone Hand No 7, which connects to the Control Units via the cone shaped rubber plugs, referred to as ‘snatch plugs’.
Finally, some general views of the WS19 and WRCUE set up.
The lid of the WRCUE is hinged and once set up the top can be fastened down as shown,
just leaving the front open. As the WS19 operator has to stay with the set, the WRCUE is placed near the set in use.
A typical setup would be with the remote control on top of the set as shown or in front of it. I have shown the Control Unit
No 2 placed on top of the set, however, in a vehicle this box would be permanently bolted somewhere inside the vehicle.
Power supply unit No42.
Power pack for a military vehicle radio. Power supply for the Burndept BE201 radio.
This was a commercial aircraft frequency radio, usually used linked to an Army Wireless Set 62 to
provide relatively mobile air-to-ground communication. Prior to this the Army used the
Burndept CN348 radio with the WS62. The next picture shows the position of the power unit when set
up in a truck its at the top right of the picture. Thanks to Rob and Steve on the war traders guild
for this information.
