Cool. It’s new to me though.
I would like to see a fully automatic .500 Wyoming Express.
That would make for an interesting “hey Bubba, hold mah beer a second” moment.
If you find a LeMat, a REAL ONE, not a replica or a forgery, you have a really great treasure in you hands. Only about 4000 or so were ever made, in France, and they were primarily used by Confederate officers as side arms. IIRC, a real authentic one goes for as much as $50k, so beware, there are forgeries that are really good. Look for machine made screws that are definitely NOT made in the 1850 - 1870 time frame..........
