I believe that the background of xausa´s initial question is the statement of Dorleac somewhere on this forum. He wrote that Mauser used to take only large ring/small shank actions when dovetailing the front receiver ring for a scope mount. I appreciate very much Dorleac´s deep knowledge of Mauser actions and rifles , but in that case I have to disagree. It would imply that the engeneers at Oberndorf mistrusted the stability of the action after slotting the front ring in case of the large ring/standard shank.
#1.

They didn´t hesitate to cut the receiver ring on the Kurz Mausers single square bridge when they applied scopes with the original Mauser mount.
Wall thickness in case of large ring / small shank .155 .Smallring/small shank (Kurz action): .160 .
Not a real difference.

#2.
I have encountered a couple of single square bridge actions ,large ring standard shank with the original 3 foot Mauser mount and front base dovetailed into the receiver ring.

#3.
It is nearly impossible to determine in the case of a Suhl type mounting if it was done in the Oberndorf plant or aftermarket by a gunsmith elsewhere.
#4.
As a rule of thumb I would say that a Suhl type mount done at the factory is an exception and the action type (small or large barrel shank) is in no way a sign of the origin.

#5.
After nearly over 40 years in dealing with Commercial Oberndorf rifles I have learned to
avoid the terms "always" and "never"
