Re: AVO Multimeter survey
Hi Ian, i can confirm all the four Model D's of mine you mention have a 'D' Prefix on the scale plate. It's printed on, then the s/n has been painted in afterwards.
I can confirm they are all 10S/10610 meters (well that's what the instruction plates say!)
On D-5422-642, the year 1942 is NOT painted in after the serial number and date code. This meter is also different from the others in that is has the Arrow/Phaeon, not the Air Ministry/Crown logo. The feeling i got from the 1942 meter is that the scale plate and movement were replacements fitted in the early fifties. (unconfirmed) It was a real mess when i got it, with the ally back-box rotted through, but behaves the best out of them all. Sometimes the way..
