I do not believe the G98 JHV is a Mauser. If I'm remembering correctly, it's a Mannlicher, presumably manufactured in Budapest.The jhv heereswaffenant (german army acceptance code) that you listed stands for Metallwaren-Waffen-u.Maschinenfabrik A.G. Budapest IX,Ungram.in budapest Hungary.
The rifle was made in occupied Hungary. It should have a two piece stock. They are quite rare.
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
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.
$175 to $800 depending on condition and matching parts.

The GEW 98 Mauser, in 8mm caliber. See link below.
The second one is shorter
The Model 1903A3 rifle is base upon the Mauser 98 action but they are not exactly the same.
Depends on the state the rifle is in and where it was obtained. Please contact me at shikimaa@yahoo.com to discuss it.
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.
You K98 was made by waffen werke (arms factory) in Brunn Bystrica. The 'dou' is the firearm code for that company. '43' stand for 1943, year it was made...................
