I’ve got a Persian mauser carbine in 8mm,17.7 inch barrel.
The muzzle blast is pretty raw.
I remember when someone acquired a bunch of Persian Mausers. There was a write up in one of the gun magazines. They were made in Czechoslovakia and the quality appeared to be better than average.
I would have wanted one of the roughly 24 inch models. In 1977 I ordered a new, unfired model 1909 Argentine Mauser from Walter Craig in Selma, Alabama. It was gorgeous. All numbers matched except for some reason the muzzle cover. It even came with the original test target. Mine had actually been made in 1909. There were a few minor dings from being stored all those years but basically they were still brand new.
At that time the Germans were turning out military rifles which had a better finish than the majority of commercial ones. The only problem was they were chambered in 7.65 Mauser which was a little hard to find.
