Source for obsolete sxs parts?

[Rusty Goose]

I have an old Belgian 12 ga. SxS marked J. Reynolds. I gave it to my dad for a wall hanger many years ago. I'm afraid is best days are all long passed. When I found it the forearm was missing, I found one in a junk bin at a local gun show. It doesn't quite fit correctly and is held in place by the miracle of a hot glue gun. Now it has come back to me and I'd really like to find a proper forearm for it, I keep perusing Ebay, no joy so far. Anyone have an idea for a better source?

Start at Numrich Arms, alias Gun Parts Corporation. Then Midwest Gun Parts.

That's going to be a tough one.
