I have a H & R 1900 single barrel shotgun that has been in the family a long while. The shotgun itself is probably not worth $25 bucks, I would not think about shooting it. However, that said I want to restore it so it can be a nice display gun. I am missing what I have been told is the "joint pin assy, large frame" this holds the barrel in the stock. Over the years this piece was lost ? I have looked/inquired everywhere over the last year and half. I would be willing to buy the complete shotgun in order to get the part. Would greatly appreciate any help, advice, direction. I have tried all of the big part suppliers on the web. thanks.
