I'm having difficulty dating a Huebler I picked up at an estate sale -- according to the butt cap, it's a "H3I" or HI3", but I can't find any matching references online for either. Huebler is vertical on the other side of the cap. Attached are photos.
I'm considering selling my Huebler HI-3. It's in great condition, with one exception. There is a slight crack in the shaft collar (pictured). Other than that, it's flawless. What could I expect to realistically get for it if I put it up for sale?
