Default Re: AVO Multimeter survey

Your AM Type D Avometer is of Second World War vintage. This version was in production from about 1939 until 1947. (There was a previous variant made from 1938, I've only ever seen the one I have so I can't give a more exact date).

They were widely offered for sale on the surplus market in the 1950s and still appear from time to time on ebay. They are one of the most common types of Avometer of their period which appear on ebay.

From the ranges chosen, I believe that this meter was specified for use on aircraft and motor vehicle electrical systems but I would very much like to have confirmation from someone who either used it officially for this purpose or who has documentary evidence.

If anyone is intersted, I can post a detailed description of the Model D.
