Colt Model 1900 Sight Safety Serial Number 2015 - The Colt Model 1900 is the first Browning designed automatic pistol model licensed to and manufactured by Colt Patent Fire Arms Manufacturing Company. With the exception of the 200 Second Army contract pistols (that were manufactured with forward slide serrations), front slide serrations on commercial examples began at approximately serial number 2000.  This pistol was manufactured in 1901, the second year of production and is the second variation of the Model 1900 with front plunge milled serrations, high polish blue, fire blued small parts and smooth walnut grips.
