The factory letter that accompanies the revolver states that it was shipped to Lt. Col. G.D. Ramsey at Washington Arsenal on June 20, 1862 as part of a shipment of 1000 revolvers. The letter states that the revolver has standard blue finish with brass trigger guard and wood stocks. The top of the barrel is marked with the standard Colt barrel address. The left side of the frame has the two-line "COLT'S/PATENT" marking. The cylinder is roll engraved with the Texas Navy battle scene. The full serial number is located on the barrel, frame, trigger guard and back strap. The partial serial number, "4819" is stamped on the cylinder. All of the serial number markings are original and matching. The letters "P.B." are stamped on the left side of the barrel lug and on the inside of the grip strap. The significance of these markings is unknown. Faint Ordnance inspection stamps are visible on the stock heels, and single letter Ordnance "S" and "C" inspection marks are stamped on the barrel, cylinder, trigger guard and back strap.
