November 2002 maybe?

My other later models, the last four digits are what appear to make the date up, so I wonder if that "1122" is November 2002?

I picked up a very Late Model 7 Mk II recently in fabulous condition, like new.
Only defect is a missing Dust Cap on one of the PF Sockets.

Since there hasn't been a Serial Number given for a while, I thought I would take the opportunity of entering this one.

15687 7/10/76

What did grab my attention though, is that this Model 7 is about 4 Years later than
the Model 8's move to a Plastic Case and Strap, but it still has a Bakelite Case and Leather Strap.

It would seem AVO were still making very High Quality Meters well into the 70's.

Not sure when the last Model 7 rolled off the production line, we have a couple logged
from 1977 and a Model 40 logged as 1978.

Nice find! I think I have a 1970s Model 7 too.

Nice instruments the 7 mk2 is. I've got quite a few of them, dating between 50s to the 70s. What I do note is that some of the early 7 Mk2's with the later terminal types have a metal rear casing, then the bakelite made a return on the last models.

...If the paint has started flaking and the aluminium box is in contact with the strap, the natural moisture content of the leather sets up deterioration in both materials. Shed and barn finds should be checked for this as the ally rots through and the leather goes super hard and brittle. A sudden loss of altitude and crash landing can ensue.

I wonder what's sparked off the latest trend in Avo Model 12's going for near 100?

When I saw the condition and late Production Date, I decided I had to have it.
Really is a stunning example, which is lucky as it didn't come in a case.

Anyway, this has encouraged me to get back into AVO's a bit and to pull my finger out and carry on with correlating the Multimeter Survey Data.

To that end, I have now completed the first part and attached it here.
Only includes Model 7's at the moment, no particular reason for that, it's just way it panned out.

I hope somebody out there will find this useful or Interesting.
It would be a real shame to let the Data obtained in this Thread go to waste.

I'm happy to maintain the Database if people still want to post their Serial Numbers.

Would be interesting also, to hear from anybody actually using this Data.


Regards

Ian
