Hey everyone. I really need some help on the firearm below. Its what I think is an "older" model 1100. But, thats all I know. I want to put it and an 870 express on the market. But I have no clue as to the age of the 1100 and the value of it as well as what type of recoil system this thing has.Special model??? I ened up with the two in a lot of guns I just bought from a neighbor. Before I list it, I just want a good starting point. The serial # of the 1100 is M336910V. Thanks for the help in advance. The gun is absolutely perfect, no scratches and the only blueing wear is on the fore-end cap.
