The Smith & Wesson Model 3 "Schofield" Revolver chambered for .45 Schofield cartridges (which the Schofield Revolver in the game is based on) was first produced in 1875. The Smith & Wesson Model 3 itself (which was offered in other chamberings such as .44 S&W American or .44 Special) has been around since 1871 and possibly a little earlier. So yes it did exist in 1899. I have proof to back me up too: Smith & Wesson Model 3
