A Harrington & Richardson by Rossi…hammerless SxS

Have reassembled a hammerless SxS shotgun that’s labeled as a Harrington and Richardson by Rossi. What’s strange is there is no SxS H&R model that I can find any record of. There are two Rossi SxS models: one hammerless, one with external hammers.
 
In the case of this shotgun, customer indicated someone had fired 3.5″ shotshells in it when it’s only chambered for 3″ shotshells. Then it wouldn’t open. Once I got it apart to figure out why it wouldn’t open, found the 2nd (top) barrel lock pin was broken off so that the release lever didn’t pull it from the thru hole in the top of the barrel.
 
Here’s a picture of receiver, the release lever, the broke pin, and the pin I fabricated to replace it.
 
And yes, there’s a bottom barrel lock too.
