I've got a few 220's in my collection, everything except a 28, and also an early one-pin 219 in 30-30. I've replaced parts in those, working on an Eastern Arms 12 gauge barrel now with a broken ejector spring lever.

I have a problem child here, a 219C in .22 Hornet 2 pin receiver, that I can't get to function in no way, shape, or form. Oval SP stamped, giant H stamp on the receiver tang, barrel stamped underside in W V, a flame and an anvil which I assume is a proof mark. Barrel date code is a 1K... It is cut/grooved for a scope.

I have asked around, and looked around, and have not been able to find information on the 2 Pin receivers. I've looked through some old Numrich catalogs, browsed the net, you name it. My go-to guy is stumped. This gun was in my dad's safe and I want to restore it and keep it in the family. At this point, it's disassembled and I can't find a schematic to even know if I have all of the parts. Was this a "transition" model? It looks different inside than a 219...

Any links or advice would be duly appreciated.
