The U.S. Navy contracted 5,000 of Colt Model 1889 revolvers and out of the 5,000 there were 4,637 that were returned to Colt for conversion to the 1895 cylinder and locking system. This particular revolver is one of the 363 that escaped the conversion and remains unaltered. The top of the barrel has the two line address/patent dates (1884, 1888) marking. The rear of the cylinder is marked with a star, the letter "P" and the assembly number "4009". The number "4009" is repeated on the inside of the frame, crane and underside of the barrel. The butt is stamped "U.S.N./[anchor]/38DA/No/3770/P/W.W.K./1889". The left side of the frame at the rear is stamped with a five-point star, which is repeated on the cylinder latch, crane and rear cylinder face. Fitted with smooth grips, which have the "4009" assembly number on the backs. The U.S. Navy leather holster has "USN" embossed on the front of the flap.

Fine. The revolver retains 40% original blue finish with a smooth brown-gray patina on the balance. A few patches of minor pitting is present. The grips are fine with some minor handling marks. Mechanically fine. The holster is good with age cracking. This model of U.S.N. Colt Revolver is very rare and much sought after!
