I am trying to compile an unofficial history of the AVO multimeter (unofficial beacause there is no official
interest in the project).
I doubt if there are many Forum members without at least one AVO, so there should be enough material for me 'out there'/'in here'.
If each of you could let me know the Model & Serial number of any AVOs in your possession, I should be able to derive quite a story from the information.
I'm sure that many of (y)our multimeters were, er,
liberated 
, so in order that they and their owners remain untraceable 8) I suggest that all but the first digit of the first number group be replaced by Xs.
Thus my 8 mk2 54112-C-1256 would become a Persil-white 8 mk2 5XXXX-C-1256. (The letter and the numbers in the last group
are important ).
If you post your replies in this thread everyone will be able to see how the survey is going
. If you're bashful
you can use the PM channel.
It doesn't matter which model you have - the older the better for my purposes - if it's got a serial number on the scale plate I'd like to know about it.
I'll post any conclusions so all who contributed can say " I was there on St. Crispin's Day " .
Thanking you, as they say, in anticipation.
Cheers
