SN 919xx would date its probable shipment at 1906-07. If it has the rounded butt, it would be a Model 1902, and with a square butt, a Model of 1905. Most of the 1902s are seen with the black hard rubber grips, and replicas of that style abound. The "MADE IN USA" stamp was not used until 1922. Out of curiosity, what does the caliber stamping on the barrel say?
