Inspired by the very rare and extremely sought-after 1st Generation Colt pistols inspected by US Ordnance Department Principle Sub-Inspector in Charge, Henry Nettleton, Cimarron Firearms recreated the Colt Single-Action Cavalry Model with his unique inspection initials. The Cimarron replica of the US Cavalry 1873 model a 45LC single-action, six-shooter with a standard blue finish barrel with walnut grips; Nettleton placed his inspection stamp on the left side of the hammer and trigger guard, unlike any other inspector.
