Mainly a pinfire cartridge and pistol collector but picked this one up recently and thought I would share it!
I would like to better date it and figure out what the other proofs are.
Some info from Guillaume Van Mastrigt says that
The broken gun with the LF logo inside a rectangle with a rounded edge was used by Casimir Lefaucheux until his death. Then his wife used it until selling the rights to the name, Lefaucheux and the logo to her son-in-law, Laffiteau in 1859.
In Nov. 1865 Laffiteau filed for new trademarks with the LF and the word Lefaucheux.
So this gun was either made (or sold by) before 9 Aug 1852, by Casimir Lefaucheux
after 9 Aug 1852 and before 1859 by Casimir's widow
or after 1859 and before Nov 1865 by Laffiteau.
The other marks make it more interesting.
There is a FASSIN 
Which is potentially FASSIN-RONGÉ of Quai Davroy, 582, LIEGE, cira 1836 - 1888
And an L, which could be anything; Lefaucheux, Laffiteau, etc 
And a JLR which is maybe
ROUMA LJ. ?
And a 1244 which appears on the barrel and the receiver (under the LF 2773)
Anyone have any thoughts or comments?
