Need a little help. My son-in law(a non hunter or shooter) has an old Mod. 37 Ithaca he wants to get rid of, but we don't have a clue what it's worth. It's a 20ga field model that's not in real good shape. The Modified ck. barrel has been cut off with a hacksaw to 23 3/4", the receiver has been drilled and tapped for a scope base. As he lives in NY State we suspect someone tried to make a deer gun out of it. The serial no. is 237xxx. I believe it has little or no collector value, but it could be a good light rabbit/grouse gun. Any help on the value will be appreciated. Thanks in advance, Clydep
