Vintage Amplion Pocket Volt meter Model 33A 

This 1920s/ 1930s Vintage Amplion Pocket Volt meter Model 33A is a wonderful little device. It has a white Ivorine back with chrome surround, and was made by Amplion. It comes with its original box, which has discoloured with age.

The unit has not been tested and is being sold as a collectible, for display only. It is in very good cosmetic condition but with a few scuffs and some loss of chrome coating, commensurate with age and use. 

A nice addition to a vintage technology collection or would make a great desk ornament with suitable support: (It is unable to stand upright unaided).

The pocket Voltmeter measured the following:-

0-25 Milliamps
0-250 Volts (R=10000Ω) high tension

Ivorine is an unusual type of plastic made from formaldehyde and casein protein extracted from skimmed milk. It is highly susceptible to moisture and is easily discoloured.

Amplion was the trademark of Graham Amplion of 230 Tottenham Court Road, London, W1: a subsidiary of Alfred Graham & Co. They are best known as manufacturers of Amplion loudspeakers, public address equipment and wireless receivers.
