Mauser k98 Barrel with rear elevation adjustablesight in great condition RARE!!

Description

Chrome inside barrel shows no use whats so ever ...I'm sure if its even been used !  end to end it is 23 inches so my guess is that it is a carbine barrel.   If my description is wrong, please correct me as I need all the help in id of this barrel.
I am not a barrel expert, just a gun person.   Comments below are from Ebayers smarter that me when it comes to barrels!
Barrel chambered in 8mm    Thanks to a nice EBAYER
Note:
This is post WWII Yugoslav not German..this info was sent to me from a nice EBayer..thanks        Note:  info from a eBayer  thanks
All Yugoslav barrels have a shoulder on the face of the chamber and this has none.It appears to be a reworked 1903 Springfield barrels given to them by the US government
