Kreigsmarine Spannungsmesser by Hartmann & Braun AG

Manufactured in 1942, this electrical voltage meter comes complete in its original fitted box which is marked with the H&B logo and S.V.K. 9361. It is in excellent original condition and embossed with the same number, the KM eagle and swastika and the code Zb. While it is being sold as a collector's item, it does appear to be in working order and is complete with the original testing cables. Included is a test certificate issued by the company in Frankfurt/Main and dated 9.3.42.
