The examples of Rem 870 I have seen are completely different. The front has a brace for barrel and tube. They fully enclose the front. They have iron sights. The bayonet was the in service M7 not the long one. Remington built bayonet lugs but they seem to be scarce and I cant find one to save me. The wood was sanded walnut no fancies. The finish was park and the stampings look done by farmer John with about four strikes to the S. The U.S. should have the period and these don't look like arsenal font. Just the biggest ones they could find. The mix of barrels is like the rest, a mix. I don't think anyone was trying to do anything but build himself a combat gun and convince himself it was real. On the other hand, in it's second form you have a supreme shooter.
