1874 Chamelot Delvigne
Rather curious your “1874”, I see neither year (S XXXX right side of the barrel), neither mark of manufacture (on the right-hand side of the carcass, above the branch former of the trigger guard), nor number which must appear in 11 different sites in entirety and 19 sites in summary (the last 2 digits).
In short, it does not seem to be “lawful” not put aside the indication of the model and the 2 ringed letters of the controllers…
