WW2 Imperial Japanese Navy / Army – RADIO VOLTMETER – VERY NICE!

This testing unit indicated the current voltage of the aircraft or vehicle radio electrical system. 

Made of brass, steel, plastic, and aluminum, this item is of mid-war manufacture. Dated July 1942, it was brought back by a US Serviceman. As it is in used condition, it does feature various marks, scratches, and wear. I have not tested it for functionality, so I am selling this set as-is. Lots of Japanese writing and markings! One small chip to the plastic at the rear (see photo), but it does not detract. Would make a VERY NICE addition to any Japanese Instrument Collection!
