Chris,
Interesting, it does appear to be in very good serviceable condition all the knobs turn freely and lubricant is still present on the teeth of the gears. I would be neat if it could be used again on a hellcat, I certainly don't think I'd part with it to simply sit in someone's else's display of militaria. One has to wonder why someone would have kept this specific piece, I purchased it at an auction house with 3 1911 barrels and several new boxes of Brazilian 30-06 blank cartridges. Perhaps they saw it was produced by a well know tackle company and thought it to be neat!
Thanks
Ryan
