Gentlemen, I was looking today at a 1935 Steyr catalogue and there is one page devoted to all the custom options that were available when purchasing a new firearm. One option was a ribbed barrel. Has anybody ever seen on or have any pictures of one. I have a soft spot for Mannlicher Schoenauer rifles and spend a lot of time looking at pictures, catalogues and real guns however I have never seen one with a ribbed barrel. Thanks in advance.

Waidmannsheil.
