I have an older Ithaca 37 Featherweight 12 gauge pump, modified choke, with 2 3/4 chamber that I'm looking into selling. It's in perfect functional condition, there is no rust or oxidation, just a few scratches in the stock from normal use. I put a recoil pad on it, but still have the original butt plate. Just curious how much I can get for it. Any ideas?
