Hi I have a recently acquired model 1903 winchester model 1903 22 caliber rifle. Serial number 105210. Kind of looks like an old style rifle with the tube in the back and the cartridge slot on the side of the stock. Anyone know much of this gun? Ive tried the winchester site but I get hits on 1903 everything. Ive seen the same rifle listed on the web but I dont know much of the history of the gun. Anyone can fill me in?
