Hey guys. The piece is unloaded, partially dismantled and soaking in SafetyKleen. It's not in the river or melted down by the police. When all the varnish is gone, I'll see what kind of oxidation is on it.
Once I got all the gunk off the priming caps I saw that someone at some point had been pulling the trigger letting the hammer strike. all the priming caps were dented and smashed against the nipples. I guess they were lucky!
I took every possible precaution with this. Soaked the chambers in SafetyKleen till the primers fell right off, sealed the muzzle side of the chambers with plumbers putty, secured chamber in bench vice facing down and away into a pile of damp rags, slathered grease on all the nipples before applying wrench, eye/ear protection, long sleaves and pants, and heavy work gloves. You guys might think I went overboard, but I really have no exposure to this except reading websites and youtube. Being a landscaping equipment mechanic I've seen guys get messed up doing mundane things.
One chamber at a time I removed the nipple and forced the powder out with a toothpick and Wd-40 then compressed air. Then removed all the balls with a hammer and pin.
I think I'm going to look into firing this. My friend who is into modern rifles goes to a range that offers supervision for noobs. They also sell provisions so I won't actually have to possess anything but the gun, which is legal as long as I don't have the ammo at home.
Thanks for the concern and assisstance.
