Manufactured in 1917. The left side of the slide has the two block, two line patent dates/address with a Rampant Colt behind the serrations and the right side has the two line caliber marking along with "DR. GRAY G. HOLLADAY./U.S.N.R.F." Right frame side has the model/serial number marking. With a two-tone unmarked magazine.

Very fine. The pistol retains 85% plus original blue finish with the period non-factory inscription etched on right side of slide with the balance a mottled gray patina and some minor pitting on the grip straps along with some brown patina on grip mainspring housing. The grips are very fine with a few minor handling marks and a spot of wear in the overall crisp checkering. Mechanically excellent.
