Ken - it all "goes 'round" - a neighbour stopped by with a decrepit looking .410 shotgun that he inherited from an Uncle - stock at wrist was broken and held together with hockey tape. He wondered if I could "fix" it - was stamped as Remington Model 812. A CGN guy sold me some firing pins and firing pin return coil springs - said they were all the same - CBC 151, Rem 812 and CIL 402 - so, I assumed other parts might swap - that Rem 812 was stamped as "Made-in-Brazil".
You are not exactly "out of the woods" yet - still have to get the parts - and then they have to fit and work!!!
