I looked at a M1867 Rolling Block at a gun show today. The seller said that he had just bought it at the same gun show and didn't know much about it. He said that he was told it was 45-70 caliber. He had a bunch of reloaded ammo and some fired cases for it that were marked 50 Alaskan. It was hard to research it online on my phone at the gun show, but the markings on the barrel indicated that it was from Norway. Later at home I found a reference to some that were actually made (or converted) to 45-70 (or something almost 45-70).
He told me (why, I don't know) that he paid $225 for it at this gun show and he was selling it for $475. It was tempting, but not knowing exactly what caliber it was made me walk away.
The rifle was in good shape and didn't look like it had ever been blued. It was center fire and didn't look like it had been converted from rimfire.
Now that I'm able to research it looks like there's alot of things to look for to ID the gun.
Any suggestions or ideas on the price?
