7.65x53, also known as the 7.65 Argentine or Belgian.
It may not even fit an 1891 Mauser. Bolts are not a "drop in" part- they may require fitting (headspacing) to that individual rifle. That is where a gunsmith earns his pay.
If it is a ww2 mauser, the maker & the date made will be stamped on the top of the breech. it will look something like this bnz 43 for a mauser made in 1943 by maker bnz The caliber is 7.92 mm or sometimes referred to as 8mm mauser model 98 means it was made in 1898 and it shoots a 7.9mm or 8mm round i have one with the serial number 4101 also known as Gew 98
I don't think you have a Mauser - the flaming cannon ball is a US Ordnance marking, and both the M1903 Springfield and M1917 bear very close resemblance to the Mauser (both share a lot of their lineage with the Mauser). If it's either of these, it would be chambered in .30-06. However, these are not the only rifles to bear that marking. Feel free to send me photos (my email address is in my profile), and I can tell you more from those.
Mauser was located in Oberndorf Germany.
None.
7.92x57mm, better known as 8mm Mauser. Same caliber as the German military's Mausers.
Yes.
7x57mm
I have one and it is a 7x57 caliber is stamped on the left side of the barrel.
It MAY. The "broomhandle" Mauser was originally made for a bottlenecked cartridge, the .30 Mauser. It was later made in caliber 9mm Parabellum.
It may not even fit an 1891 Mauser. Bolts are not a "drop in" part- they may require fitting (headspacing) to that individual rifle. That is where a gunsmith earns his pay.
"No, 7.92 is German military caliber for WW 2 and earlier Mauser rifles." Actually, 7.92x57 is the same thing as the 8MM Mauser, if that's what the person was asking.
The value of a .22 caliber single shot Mauser gun depends on its condition. This gun in mint condition is valued at around 150 dollars as of 2014.
50-500 USD
