Very Scarce World War I Era British Proofed Canadian Ross Rifle Co. Model 1910 Mk III Straight Pull Bolt Action Sniper Rifle with Warner & Swasey Telescopic Sight and Scope Case Manufactured c. 1910-1916. The Ross Rifle was invented by Scotsman Charles Ross and manufactured in Canada with several different variants from 1903 until the middle of the First World War. Though largely surpassed by the British supplied No.1 Mk III* Short Lee-Enfield for use with Canadian infantry on the Western Front, the accuracy potential of the Ross design made it a suitable platform as a sniper rifle, with a number being converted for use with telescopic sights like this British proofed example. It features winged blade front sight, a Long Lee-Enfield type B.S.A. Martin patent period replacement folding ladder peep rear sight, British proofs marked on the chamber and receiver ring, and "ROSS RIFLE CO./CANADA/M-10/PATENTED" marked on top of the receiver ring. Matching full arsenal added serial numbers on the receiver and bolt handle. Importer marked on the left exposed interior receiver. Fitted with a smooth walnut handguard, a walnut stock with various stamps on the right side of the butt including a "1916" date and white painted "35" rack number, and a mounting bracket screwed onto the left side of the receiver for the included Warner & Swasey telescopic sight/scope, which is complete with the a rubber eyepiece and marked "TELESCOPIC MUSKET SIGHT/MODEL OF 1913 No.6740/THE WARNER & SWASEY CO." on the left side of the body, with a matching serial number to the scope stamped on the bracket. Also includes a leather sling and a "DIAMOND "D"" marked period leather carry case for the telescopic sight.
