Out of 500 about 20 are known to exist now; the rest were scrapped late in WWII according to published research. Original leather case made by Hugh Carson Ltd.
Of Ottawa, but number is for a different scope; hardly any of the survivors match. Case is somewhat stiff from age, but has sound stitching, hinge, belt loop and top strap.The serial number is 310. That number also appears in another location on the scope body under the original enamel.
Original range dial is marked for. 303 ammo out to 2400 yards. McBride, "A Rifleman Went to War". Just for perspective, about 30,000 No. Thanks for looking and feel free to ask questions.
