That's a rare one.  The BD-86-A is the 14 vdc dynamotor for the BC-307-A 10 watt A1/A2/A3 1500 to 8100 kHz aircraft transmitter, part of the 1936 GE SCR-238-A.  There aren't many parts for that set still around.

Mike Hanz has a BC-307-A and BD-86-A under restoration:

I bought a BC-307-A at the 2017 Birminghamfest for $200.
