With the bearing target sighted through the "V" atop the glass prism, the observer would read the direction of the bearing through the prism mirror as it is reflected up from the compass card. The markings on the compass card are reversed so that they appear correctly in the prism mirror. |

American WW11 computer true airspeed. |
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.
