Check your bolt face.A second indicator is the serial number. All 1893/1916 rifles have this rib and also the bottom of the bolt face will be squared off. By blowing up your picture I believe I see a rib in the left side of the receiver. The reputation they earned on the South African veldt over a century ago would seem well deserved.There are a couple of indicators I see in your photos that point out (to me at least) that you might have a Spanish Mauser of 1893/1916 vintage. They were rugged, accurate, and reliable guns, and I know why "die slim kerels" (the crafty fellows) of the Boer commandos thought so highly of them. I found the Model 1895 Mauser to be a well-made, excellent-handling rifle. Running five rounds of ammo across my PACT chronograph gave an average velocity of 2,728 fps. Once I had the measure of that, I fired four targets, with my best having a well-centered 2.75-inch group. With a minimum rear sight setting of 400 meters, it took me a few shots to figure where to hold to put rounds on the target. Loading with chargers was quick and effortless, and rounds were chambered and spent cases were extracted smoothly. The narrow rear sight notch required care when aiming, but aside from that the Mauser's handling qualities were excellent. The Mauser was fired on my club's 100-yard range using Remington 7mm Mauser ammunition loaded with 140-grain softpoint bullets. 1893 was the first Mauser to use a staggered-row magazine, which permitted the magazine to be charged with less effort, fed cartridges more smoothly, and since it was completely enclosed by the stock, was almost impervious to damage. Very few were made as it was superseded by an improved rifle within a few months. It had a new-style nonrotating extractor that prevented double feeding of cartridges and made bolt manipulation much smoother.

The first Mauser chambered for the 7x57 was the Mo. The bullet had a high sectional density that gave it a flat trajectory, long-range accuracy, deep penetration, and light recoil. The original load consisted of a rimless, bottlenecked case 57mm in length with a roundnosed, 173-grain FMJ bullet traveling at 2,300 fps. The 7x57 cartridge was one of the many smokeless powder rounds developed by the Mauser company during the 1890s. But just as important as the improved rifle would become, the cartridge it was chambered for would become even better known. Mauser's R&D work resulted in the development of an improved bolt and new-style magazine that held cartridges in a staggered, flush-mounted box.
