That looks exactly like my 1873’ Charles Daly. Looks like a plain Jane non fancy side plate design. All I have is an outline going around my side plates and it says Charles daily on each side. I also have “flash pans” (is what I think they are called) below my firing pin strikers on each side, which it doesn’t look like you have on yours. The members here narrowed down the year of my gun here years ago due the release lever on the fore end. The only numbers I remember have on mine is the number 65…if I remember. I have to pull it out of the safe and look again. Maybe I do have another number like yours. I just don’t remember. There is the number 65 on a few of my parts. One of my hammers was missing and the other one was broke and brazed back together. I ended up buying a pair of replacement hammers from Dixie gun Works and had them installed. So not original hammers but the rest is all original. The original hammers had a rounded off. Yours have a flat finish on the front so they’re a little different than mine. Restored it myself accept for the hammer install. The plans were to made it a shooter. It’s Nothing fancy, just an every day shooter. It is what my plan was since day 1 because it wasn’t a fancy engraved firearm (an entry level gun) that would probably never be worth an arm and a leg. Imo the shape your gun is in it’s going to be of more value to someone just to hang on the wall then restore and shoot it unfortunately.
My barrel to action fit wasn’t as tight as I wanted it to be so I shimmed it with some aluminum barstock. It locks up pretty tight now. Like above if you don’t know what you’re doing it’s not hard but take it to somebody that does.
BTW I bought mine at a rummage sale in the late 90s/early 00’s for 45 bucks…lol. When they’re in rough shape like yours and mine “was” before being restored, imo they still don’t bring a lot of money today that I’ve seen. Most people seem to buy them to hang on the wall for a conversation piece and not shoot unlike the selected individuals here. Unless you stick it on GunBroker and more than one person wants it…you might get lucky and get a bidding war. If you’re trying to get interest here which it sounds like you are to sell it I’m sure somebody would probably be interested to buy it but in the condition it’s in. I don’t think it’s gonna bring a lot. Imo can’t do the work yourself. It’ll probably cost you more to restore it than what the gun is worth. Either way it looks like a nice gun and a nice project for somebody, or if it’s sentimental value, I would just hang it on your wall if you don’t have the ability to repair or restore it yourself.
