Stock, bolt handle, long cocking piece, triggerguard size and shape, tangent rear sight and the front-sight base are all pre-WW1/1912 Mauser commercial shape. The lever and the push-button release floorplates came only in later. On Mauser round barrels the front sight base was not integral, but merely soft soldered on, so there is no problem in removing or relocating. Only after 1913 front sights were soldered on with a band around the muzzle. Though the barrel may have been shortened or not and a new band swivel base added, such an early Mauser commercial rifle with a three-quarter length stock is a rare find! The letter A,B,C,G,F designations were not yet in use at that time by Mauser. A very similar rifle is shown on page 526, photo # 805 in Jon Speed's "Mauser Archive".
