I've seen a couple pictures of these but can't find any good information on them.
Are they real and if so is there a good way to authenticate them?
The only marking I have seen to denote them is opp stamped on the side of the stock, which would be trivial to reproduce.
Does anyone here know much about them? Or some place I can read a little about them?
Thanks
