Yeah, like Jani I think production between WWI & WWII. Don't know why but many hold his offerings in high regard. Looks as if the firm was still peddling sporting weapons post 1971. I too agree that this was sourced from the pool in Ferlach but from time to time one sees the name of other gunsmiths paired with Karl Goluch. He may have been an intermediate source. If it hasn't been re-touched, it is in top condition. The Prima Gewehr Lauf Stahl Fried. Krupp Essen is more than likely Ferlach recipe for Suhl's Weapons Grade Krupp steel. Just advertising for the most part and there may or may not be a difference in composition. Length of pull is quite short. I'd want to confirm the tubeset length as it should be an integer length like say 72cm, although a 1/2 integer like 71.5cm is possible.

He looks to have been at Herrenstraße 50, Linz.

Kind Regards,
