In addition to the standard or "plain finish" model, a deluxe or "fancy finish" model was offered with checkering on the forearm and wrist of the stock. The plain finish rifles were offered in 1910 at a list price of $30.[3]
Winchester factory records show an order placed in 1915 for 150 Model 1910 rifles, spare magazines, and 25,000 cartridges of .401SL ammunition by the firm of Andre, Schaub & Pioso as an agent of the French government. A subsequent December 7, 1917 order of 400,000 .401SL cartridges is believed to indicate additional Model 1910 rifles were acquired by the French Republic through other means.[4][5]
They were carried by aircraft observers to ward off fighters, a step between pistols and dedicated aircraft machineguns. They were later gradually replaced from 1916 onward by the .351-caliberWinchester Model 1907s. The Model M1907 rifle won out because it had been adopted in larger numbers and because it was also adopted by Britain's Royal Flying Corps and Royal Naval Air Service.
Winchester records show orders of about 500 Model 1910 rifles by the Imperial Russian government dating to 1915 and 1916. Further details are not available regarding orders of .401SL.[4]
