Not sure that the ranking is very accurate, though it could be. Reason I say that, is that I was doing a little research on my rifle and found that the Oberndorf Mausers only comprised 7% of total production, and made about 120 years ago. Just that is survived around 40 years to get converted to an M38 style makes it slightly less common. And then still here being one of the early made M96/38, is a bit of a feat itself.
