1930s OK Pocket Radio 8v & 160v Voltmeter and 0-32 Milliammeter

This 1930s OK Pocket Radio 8v & 160v Voltmeter and 0-32 Milliammeter is a wonderful little device and comes with its original box! 

It has a white face and a chrome surround and was made by OK in Bavaria: it is marked ‘Foreign’ but has an English Patent No. 280946 dating to 1928.

The  pocket multimeter measured the following:-

0-32 Milliamps
0-240 Volts (R=5000Ω) high tension
0-8 Volts (R= 250Ω) low tension

The unit has not been tested and is being sold as a collectible, for display only. It is in fair cosmetic condition with a few scuffs and some loss of chrome coating commensurate with age and use. Its test lead is slightly frayed.

A nice addition to a vintage technology collection or would make a great desk ornament!
