Your acquisition was well worth $1200. Some of the brand new Italian reproductions can fetch almost the same amount if it's the rifled version with the fancy rear sight. Be happy you have the ramrod for it. The '42 Harpers Ferry model (1851) that's been in our family since way back when has always been missing the ramrod. It's a smooth bore and has the low front sight blade. The trigger and lock assembly is still very crisp and strong. The cone is clogged up and rust welded to the barrel, thus not shootable. The one you have there looks like you could test fire it and if deemed safe, join the N-SSA. Lots of the members are now shooting original 42's these days in .69 competitions. The loads require a lot of black powder and casting your projectiles requires 100% lead (like everything else muzzeloader) and lots of it.
