Yesterday, I bought, for the bargain price of £15, an Avo Meter 12, ex-RAF, still in its leather box, albeit without leads.
By the side of it was a mint condition Model 9, complete with leads and all accessories in its leather tool roll for £42. I was sorely tempted.
It's hard to believe I was using one of these in the early 90's, they look to be a tool of the 40's and 50's.
