Hello,
I just bought a nice box with "Universal Avometer" on its front plate
but I am a little bit confused about its age. It looks to be "Test Set Multirange No.1 High Sensitivity" - due to this text on the scale (and 1-3-10...3000 range), but I am unable to locate valid SER.No to know its age. There is a
Part. No. 13574-80 in the right bottom corner of scale and
SER. No.5967 (but these numbers are handwritten, over-stroked and replaced by numbers
5336) in the left bottom corner.
Is there any chance to help? If you need some pictures, please let me know what detail can be useful, I will upload them.
Many thanks in advance,
Richard
