Thanks to Rob on the MCN for identifying this item for me. Case, Carrying, Antennae Rods, No 5. Dated 1948.
It was used with the Wireless Set No 31 (introduced 1948). It is 2 feet long and 4 inches wide. It has three pockets. When you open the top flap there are two pockets one goes the full length the other is only 4 inches deep with its own press stud fastener. The third pocket is at the bottom and ten inches deep on the back are three straps one at the top that looks like it is a belt loop and the other two look like they have had the buckles cut off?

Lewis automatic machine gun ammunition Pouches dated 1940. Mainly used by the Home Guard and for airfield defence the Lewis gun saw continued service as an anti-aircraft weapon during the second world war..

Lanchester magazine pouches dated 1941. They were created when the navy replaced the p19 with p37 webbing as the p37 basic pouches were not big enough for the lanchester magazines and the Lanchester itself was developed by George H. Lanchester and manufactured by Sterling Engineering Co between 1941 and 1945. The pouches are roughly 14 inch's high 3 and a half wide and 2 inch's deep. With three internal compartments to hold the 50 9mm round magazines of the lanchester sub-machine gun. They came in pairs left and right the right one has a small pocket on the front for a magazine loading tool the left one does not have this pocket. On the back are three attachments the bottom one for the belt the middle one for the L strap hook and the top one as a steadying strap to hold the long pouch against the body during movement or when prone. They were issued to the Royal Navy and the RAF but were mainly used by the Navy. They were not only used with pattern 37 webbing they were also compatible with patterns 19 and 25. When the Lanchester was replaced by the sten a lot of these pouches were cut down to fit the shorter sten magazines the magazine tool pocket was kept and they either cut off the top and re stitched the closing flap or cut off the bottom and added a reinforced section. The forth picture shows a Canadian commando using lanchester pouches.
