Produced in both repeating and single shot varieties, the Collette Gravity Fed Pistol uses a novel mobile chamber/breechblock assembly in conjunction with a fully contained cartridge comparable to the Hunt/Volcanic Rocket Ball. A groove runs along the top of the breech for a cartridge to be placed, and when the hammer is cocked the breechblock lifts into position for the cartridge to slide into the chamber, and then drops down to the firing position when the hammer is at full cock. A dovetailed blade front sight is installed on the muzzle, with a deeply cut notch in the breechblock. Liege proofs on the right barrel flat, and the serial number on the underside of the barrel. Sharp engraving is present on the frame, trigger guard and buttcap, with scenes of dogs and game birds on the sides of the frame and a sliding safety on the upper tang. With a checkered grip and a flared butt.
