An Australian friend sent me photos via Facebookƒ??I donƒ??t know what it is. The $1,200 price tag is Australian. Itƒ??s in an antique store, typically their prices are on the high side because of overhead and profit. I paid $40 for a $20 slide rule in one because I wanted it. Looks like a barn find condition-wise:

The colour suggests 'Troughton & Simms' - an English maker common in colonies

Its optical, not vernier, so post World War II

Looks to have been heavily used

Full case of accessories

The price tag is highly optimistic

Jim's answer seems good.?ÿ The black tag in the case states "YORK ENGLAND" on the bottom line.?ÿ The top of the middle two lines look like "manufactured by", but I could not sharpen the image enough to really tell anything about the next line.

In that case it will be almost certainly be labelled as "Cooke, Troughton & Simms".

if Lewis and Clark had used that, it still wouldn't be worth 1200 dollars... Well maybe it would...

$1200 Australian dollars is currently equal to $835 US dollars. Still at least double any possible real value, I think. It has definitely been through the mill, but that patina is just the thing that gives it value as a display piece. It's an ornament, not a working instrument. ?ÿ

not a working instrument. ?ÿ

most of that patina looks like case rub - spent a lot of its time in the case between jobs...

I recently purchased a T1A. It was a contractor's instrument and he wanted $200. I looked through the optics and it was so pitted that it would need a lens replacement if it was ever put into use. So I offered $100 and I think this instrument might be in that range. But setting it up and looking through it, testing out the motions, ect. would be important if that price tag is even considered.?ÿ

And the case looks moldy.?ÿ
