Quote: That block looks just like the one in my 71 Springfield. If you do not fined the part perhaps we can get one made using mine as a pattern. However if you fined a source for 71 Springfield parts please let me know as I am in need of a trigger guard.

Unfortunately the block came in as you see it, with a batch of various other mixed RB parts from an estate sale, a dozen years back. The block is a perfect fit for my first generation RB frame, and matches up good to all the other parts.
I have been told it was a block from a Springfield 1871 model, and that the particular design was for quick and easy change out of the firing pin in the field, but I have seen a few seemingly original Springfield RB‘s without this block design.
It makes one wonder if military armories had a problem spreading their parts around from gun to gun, like a communicable disease in a Shanghai whore house?
The Springfield Model 1871 Rolling Block U.S. Army rifle was manufactured in 1871-72 by Springfield Armory, using the design originated by Remington Arms Company, under a royalty agreement. The Model 1871 production was limited to 10,000 rifles in .50-70 caliber.
I’m like you If anyone knows of a source of original Springfield RB parts, engrave their phone number on the inside of your frame for future reference, and then post it here.
“Exblaster” if possible, could you get a couple of snapshots of the pin retainer up close, so I can see how its constructed, if it presents too much a hassle, don't worry about it, I'll bluff my way through. Tex Dooley
