Westinghouse meter, 2" dia, 15VAC full scale 600-800 cycles. USN Type CAY-22082-A. Filament meter from TBY perhaps? Good condx, a little dusty, no sign of use, movement is free, conductivity between terminals; otherwise untested. Would like to trade for either of the meters for RAK/RAL, or failing that, some interesting trifle. 73, ian K3IMW
