According to my copy of Scott Duff's book , the actual production figures are real sketchy . 150 of them were ordered from an ordinance unit of the 6th Army in the Phillipines . Later , 15,000 were requested from the Ordinance Dept. Who knows how many were actualy produced . Testing proved that the rifles weren't everything they were hoping for . Reliability suffered , more recoil and muzzle flash . According to Duff , anybody claiming to have an original Tanker would be hard pressed to prove it , as few survive today .Don't recall the actual production figures on the T-26 and I don't have access to my library now (laid up in the hosp) but I think the gun is described in Scott Duff's book. All I can remember is that the Army's short Garand is officially known as the T-26 and was a very small number of prototypes made up for testing and never ordered for production. Any "Tanker" Garand you see for sale outside a major auction house is a commercial model. One of the best is the Mini-G from Shuff's Parkerizing.
...As far as we know, this one is pre 1930.
