What is the value of a model 37 Winchester steel built shotgun?

As a gunsmith, I have had several in my shop for repair and/or reconditioning. They are a good solid field grade gun, nothing special. However, it seems that there seems to be some collector interest devoloping. I have seen them sell for $50 to as much as $150, with the 28 ga bringing $275. The value of the gun is an open ended question. The value depends, of course, on how much you can get out of it. No gun is worth more than someone is willing to pay. Reed's Gun Shop
