Re: AVO Multimeter survey
A Heavy Duty Avometer serial number from eBay for the survey: 2484-679. It's an ex BR Railway Signalling version in what looks like very good condition.
Another item of interest is a Model 40 movement with the serial number 403345-243 R which has a block magnet. I take this to mean that it is a post 1947/48 replacement for a a 1943 Model 40.
There are also batches of Model 8 scaleplates for Marks IV, V and 6/7 on offer if anyone is interested. (I hope that it's permissible to mention this here).
