I haven't been able to Identify this through my research. I has been passed down to me through the family. On the left side of the barrel ACIER FONDU is engraved into it with an unidentifiable symbol above it. J SAGET NEW is engraved to the top of the barrel. On the cylinder is E over LG encased in an oval with an unidentifiable symbol below it. also on the cylinder is what i believe to be a crown over AF which is also on the frame above where the tip of the trigger folds to. on the front of the frame where the trigger folds to is the number 72 and on the top part of the front of the frame is the letters LF. the ELG symbol has lead me to believe the gun was made between 1811 and 1892. J SAGET NEW I believe is the blacksmith Julian Saget who worked out of New Orleans between 1841 and 1880s. If anyone could provide more information I would appreciate it.
