Older German drillings are marked by bore diameter not grove diameter so a 9.3x72R will actually be stamped 8.7/8.8 and the dimensions can be all over the place. Mine(1907) is Groove .364 bore .344 tall narrow lands and I know of a couple that are Groove .358(handy though). There is also a 9.3x72R Sauer that dimensionally more like a 9.3x74R although usually not constructed to handle the power of the 9.3x74R.
I really like them and use them a lot. One of my favorites is a 1926 16ga/16ga/6.5x58R Sauer & Sons that I use for coyote hunting in heavier cover. It is only marked by the vendor(Wilkes) not the manufacture.
My 9.3x72R is a unmarked hammer drilling and is a great bird gun,
