If you are close to Lodi, Ohio...
swing by the "Log Cabin" shop during the week, Dan Kendig maybe able to ID it or know who can.
There are four variants of the Trapdoor:
1865 First Allin conversion [ this model used reline / brazed barrel inside the .58]
1966 Second Allin [Both in 50-70 cartridge, this model used specific made barrel]
1873 first true 45-70 variant with new parts not CW left-over as above]
1880's variant that had both the rifle & carbine barrels and rod bayonet.
