Re: Aircraft identity. Help needed please

Peter,

The Dubilier component appears to be a mica capacitor which was used in radio receiver and transmitter circuits. If a radio chassis can be recovered, it would have a metal tag attached to the rear of it with the name of the manufacturer. WW2 aircraft radios made in the U.S. also used metal vacuum tubes and special sockets to keep the vacuum tube locked in place. Any of these items could provide a clue to the origin of the radio. Also, U.S. and British vacuum tubes were different enough that if one were still intact, it could be identified as to origin.

Regards,

Bill Martin
