I saw an Trapdoor for sale online. Lockplate is dated 1884 but i can't figure out what sight it has, also looks like it is put on backwards.
Thanks for any info.

Looks like a parts gun to me. Sight is M1873, installed backwards.
The screws holding the lock on and the hammer screw are the square profile of Civil War muskets.
The hinge pin is the longer post 1879 part, while the receiver and breech block are the slightly narrower pre-1879 parts.
1884 dated lock plate (on the side of the gun, with the hammer) are ALWAYS after market parts made up by surplus dealers. Breechblocks dated 1884 (the "trapdoor" part that flips up) are arsenal parts used intermittently from about 1884 onward.
I'd recommending passing on this as a collectible, but probably okay for a "fun gun" or wall hanger.

Funky stock and .50-70 hammer, too...
