The Model 1903A3 rifle is base upon the Mauser 98 action but they are not exactly the same.
I don't believe so
The second one is shorter
For which nation? There were different countries with different rifles. US- 1903 or 1903A3 rifle, and the 1917 rifle Britain- SMLE Germany- 8mm Mauser 98 Russia- 91/30 Mosin-Nagant
More information is necessary. If the rifle has a 4-lug bolt head, it is the same as a Mossberg 810. Research the 810 for info on this rifle. It may be made on FN Mauser 98 actions, in which case it will be like any other Mauser 98 sporter. Otherwise, it will be German made by Heym and is either the same as a Mauser 2000 or Mauser 3000 action. The scope, on the other hand, is almost impossible to describe these days. It will likely have Japanese optics.
The Mauser Gewehr 98 was created and produced around World War I. Often times, people will say M98 to denote the Gewehr 98 or K98k. This is true because they are referring to the basic design. On the other hand, Mauser is currently producing some new, modern versions of the Mauser 98 action. This model is known as the Mauser M98. Hope this helps.
The Mauser 98 action and the Sears M-50 action are not the same; they have different designs and operating mechanisms. The Mauser 98 features a controlled round feed system and a specific locking mechanism, while the Sears M-50 is a variant that may incorporate different features influenced by other designs. If you're looking to interchange parts, you will need to consider compatibility, as they have different trigger and sear assemblies tailored to their respective actions. Always consult the manufacturer's specifications or a gunsmith for accurate assembly needs.
Your question is???
Mauser 98 from WW I.
Mauser M 98
All mausers are different because of the different models that were made for different nations. The Mauser Model 98-29 was manufactured in Czechoslovakia for the Persian Army. Based upon their requests, the rifle is longer than most and would be about the length of a Gewehr 98 in World War I.
Requires professional appraisal
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
