i keep pretty good records of unuasal thermom sales and auctions....i saw this one last year on the computer sell for 250 in really nice condition.....i would expect to see a price tag of around 400 retail or at a show.....and i would guesstimate yours at around 100 due to condtion

see me at Mason Dixon Gas, Spring Carlisle M114-115, and Hershey C4E-35.
