It looks like an "1873" to me. Although the "18" is basically worn off.
The band spring slots have been filled-in and refinished, however they are also in the wrong place for these barrel bands.
Either the stock is all wrong, or the barrel bands are wrong. Can't say.

Thanks for this information!
Cool, thanks!
Additional marking -
- Under the stock, there is a line on receiver and barrel which line-up (surely for barrel>receiver mounting reference), with a small "D" next to it.

Just noticed on the Lock plate, there's an "O" to the right of the "C".
See it?
