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.

Fine with 75% of the bright original high polish blue finish, showing areas of brown patina, bright edge wear and scattered handling marks. A mixed gray patina is showing on the casehardened parts, with traces of brown protective grease in the low areas and good detail in the engraving. The grip is good, with some space between the frame and the leading edges, a few mild dings, and excellent checkering and grain. Flecks of white paint are present on the metal and wood. Mechanically fine.
