Default Re: AVO Multimeter survey

Hopefully, this is of interest.

An almost Mint example of a Pre War Model 7.

7116-233

So November 1936 and actually, currently the oldest Model 7 in the Survey,
unless anybody has been holding back on their Serial Numbers!


Points of interest are the Temperature Compensator which is a slightly different
design from what I've seen before and it appears that the Battery Bay, may not
have originally had Brass Contact strips.

Difficult to tell, but the Battery Bay is virtually Mint, and there are no Marks in
the Bakelite where the Brass strips would have bolted down.
Looks like just the Brass Screws and Nuts might have been used for the 9v
contacts on their own.

Clearly, this Meter has lead a coverted life and I'm told, it has been in the same
Family since New.

Amazingly, the Case just popped off without any hassle.
Black Crinkle Paint 99.9% still intact.

Build quality is very good.

An absolute Time Capsule of a Model 7.
