Jeff:

I realize that the LeFaucheux is earlier, but it can't be all that much earlier, and suspect the serial number on the LeFaucheux to be in the earlier pre-mechanized serial number set. The cartridge would suggest post 1871 for military and probably post 1876 for sporting. If the components suggest Sauer source, I might concur, but I think it was made in Zella Saint Blasii for now.

Kind Regards,

Raimey
