Thanks tucker taking a stab!
From looking around on the web I guess it is considered a field gun. It has wood stock and foreend. The only thing I noticed on the markings was the "Super 90" and "M1." It had the high-vis red bead. It shows signs of use, dings and dents in the stock and foreend. The bore was not pitted, but not shiny either. I assume these guns came with five choke tubes? I guess these are $20 each? How would I locate the manufacture date?
