Unmarked M1867 Remington Rolling Block

[iron sights]

Attached are pictures of a black powder Remington rolling block I got recently with a yatghan bayonet made by Alex Coppel of Soligen that appears to be stamped with a crown. I believe the bayonet is Danish but am not sure that it is original to the gun.
The rifle has no markings except those on the tang that I've pictured, which tell me it is an M1867 made by Remington. I have taken the fore stock off and there are no proof, acceptance, serial number, or other markings I can see. The barrel and receiver do have a pair of witness marks but nothing else. I have not removed the buttstock yet so there may be a serial number on the side of the tang, but I don't think that will tell me much. I measured the bore and chamber with a digital vernier caliper and got .4285 for the bore and .5130 for the chamber. My guess is that the caliber is .43 Spanish, but I am not sure. Should I be looking elsewhere for markings? Any idea what country this might have been made for?
