This interesting firearm is an unfinished experimental double action revolver designed to automatically eject the spent casing made by Rob Roy. It has a modified ejector and a specially machined, spring loading gate. It was made using a stripped down .357 magnum Colt revolver and has no sights. The modified barrel is essentially upside down and is marked "COLT 357/357 MAGNUM CTG" on the right side and has the one-line address on the left. The frame is only marked with the Rampant Colt on the left side towards the rear. It is fitted with checked walnut grips with silver Colt medallions. The underside of the grip panels is marked "0646". The rear grip strap is serrated. The barrel, cylinder, and trigger are blued with the remaining components bare stainless steel. The blued cylinder release is loose but included.
