A lovely little vernier height gauge I picked up recently. First time I've ever seen a precision measuring instrument made in Canada. (In another of those spooky coincidences, it turns out that Mister G also owns one of these, acquired many years ago!) The only info I can find on the web is a forum where a member was seeking information on vernier caliper made by this company, and someone ventured that the company was around in the 1950's. Gone now.
Although The Duke's height gauge is Imperial, mine is metric and came in the original wooden box. The box had an Avro company label when I got it 25 odd years ago.
I have one too, how much is it worth?
I think I paid $20 or 30 or so for mine twenty years ago at a surplus store...
