Broken firing pin 1873

[Ruts]

I am the new owner of an old winchester 1873 by the serial number I think it was made around 1893. The firing pin is broke back farther than the skinny part at the end. It also didn't have a return spring although I don't know if it ever had one the pin retracts anyway although not now with the firing pin broke in half.maybe I can weld it? I shot 6 rounds today to see if it functioned and shot ok. There is a little tit on the bottom of the bolt face opposite the extractor that seems to want to stop on the rim just before the lever swings all the way closed. Other than that it works fine.it occurred to me that I would never know the firing pin was broke in half if I didn't take it apart.can I do any damage firing it like that?

Look Longhunter Supply they sold pins for cowboy 73's don't know if it's the same. Good people to deal with.
