I picked an original 1858 Remington New Army about 15 nyears ago at a flea market for $125. It is in fairly decent shape. Serial No. 55XXX. No blueing left, but strong rifling. One problem, the cylinder pin is missing the pull-out "T" that allows you to remove it when the loading lever is pulled down. AND the pin is frozen. The cylinder spins freely, but I can't get the darn thing out--I've tried driving it out from the hammer end after soaking it in WD-40, but it won't budge. Any suggestions? I have an original replacement pin and I'd really like to remove the old one. Guess I could take it to a machine shop and have them drill it out...but that could be risky. Any suggestions?
