Here is an unusual loading gate on a 7mm Pinfire 6 shot revolver.
The gate is held by a cam that you roll to the right and then pull the gate backwards.
The left side of the frame also has a separate piece to keep the cartridges in place.
Stamped on barrel: SYST. LEFAUCHEUX PATENT. with a crown.
The only visible number is a 4 on the rear of the cylinder.
Overall length is 205mm with a 105mm barrel.
Any clues to the maker and country is appreciated. I like differences like this.
