I have one, and I even have ammo for it. Fairly typically late 19th century European revolver with a few French quirks thrown in. The cylinder opens to the right, the opposite of virtually every other revolver made. Solid piece, does it's job, anemic caliber. Was in service till the end of WW2, and probably even saw LE use after that.
These are apparently somewhat common and popular in France. Fiocchi still makes ammo for them. If memory serves one of the recent terrorist attacks used one.
