I got this a while back.
Decent, used 870 walnut stock, on the face it's stamped 87M.
The Wingmaster forend in the pic was not with it, got it from someone else.
The last one I had marked like that was a Crane stock that needed some work.
As far as I can tell, the stock in the top pics was not chopped for the pad, but maybe it was just done well, or is 87M a standard stamping for the early walnut pieces?
Thanks.
