I have seen a Few with Schnabel shaped horn forends, all was in 30-06 and located in the USA. Usually had octagonal to round barrels too.

With regards to the 9.3x62 Type B on GI, it is on its way home Down Under and sold for more than $10k.

Sporting mausers demanding this kind of price tag, has got to be in exceptionally good & original condition combined with "uncommon" features eg. side safety, octagonal barrel, Single or Double square bridge action etc.
