An included Colt archive letter indicates that this revolver was manufactured in 1890, but states that the factory shipment record was unable to be located for this serial number. This is a neat example of the legendary Colt "Peacemaker" that features a smooth one-piece ivory grip and a special ordered 8 inch length barrel, with the unmistakable look of having spent time in the American West as a trusty sidearm. This is the only example of an antique Single Action Army revolver with an 8 inch barrel witnessed by this writer. The top of the barrel is marked with the standard one-line Hartford address, with "38 COLT" on the left. The left side of the frame is marked with the two-line patent dates. The matching serial number is visible on the bottom of the frame, trigger guard, and back strap, with assembly number "10" on the loading gate. It is fitted with the standard blade front sight and top strap groove rear sight. This exact revolver is listed by serial number on pages 233 and 286 of "Colt Peacemaker Encyclopedia, Volume II" by Keith Cochran, in which it is included as an example witnessed by the author; incorrectly listed as having a 7 1/2 inch barrel on page 233, and correctly listed with an 8 inch barrel on page 286. Also includes an accompanying letter dated April 9, 1989, about this revolver from noted author and Colt expert Ron Graham, in which he states, "This .38 Colt caliber, 8 inch barreled Single Action is very unique indeed, and quite probably a one-of-a-kind Colt revolver." He further states, "Total production of Colt SA's fitted originally with eight inch barrels is unknown, but they are definitely extremely rare. Therefore one should not bet his, or her, own money that there may be another original 8" barreled, .38 Colt SA in existence." Provenance: The Charles Marx Collection
