Too, I'll reiterate for emphasis to demonstrate just how far out on the forefront this platform & ammo is. Mauser actions were scarce as hen's teeth prior to the 1st Great Disagreement in Europe, without paying an arm & a leg. I am not positive, but the 11,72 Schüler arrived on the scene say circa 1907 and it sometimes is referred to as the 444 Schüler whilst the 404 Jeffery appeared slightly after say circa 1909. Now even rarer is the 11,2X72R surfaces circa 1909 and guess where it appears in a period Katalogue: Peterlongo Katalgo 1909. It had of course a very short product life, but somehow Peterlongo was @ the pinnacle of the German Big Bore technology. Also, Peterlongo went one step further and acquired a Mauser Gesteck and had it sent to Ferlach to roll out a bore in 11,2X72 Schüler just as the ammo is being manufactured. You know, a tid-bit of info might be gleaned from the Ferlach Proof facility with the preliminary data-string & the final pass nummer.
