It could mean a number of things. There's no real way of telling without knowing all of the markings on the rifle, and where this marking is placed.

The marking "SYL 850" on a Mauser rifle stock typically indicates a specific manufacturer's code and production year. "SYL" could refer to the factory or the type of wood used, while "850" often denotes the year of production, suggesting it was made in 1950. These markings help collectors and historians identify the rifle's origin and manufacturing details.
The numbers on the rear sight of a Mauser vz. 24 typically indicate the range settings in meters for the rifle. These settings allow the shooter to adjust the sight for different distances, ensuring more accurate aiming. The markings usually start at a lower range and go up to a higher range, often reflecting common engagement distances for military use.
Where it was made, proof marks, etc..
Need a detailed description of ALL markings, features,etc. in order to answer.
Assuming you mean a Mauser 24/47, use the sight as you would any open rifle sight. The slider on the rear sight adjusts for range- marked in meters.
Define 7mm. Do you mean 7mm Mauser ( a little less than 30-06), or 7mm Magnum, (a bit more than 30-06)
