because the 9,3x64 brennecke was sold by a gunmaker in Stettin wich was than a very important german harbour I believe we can assume it was bought for making a tour into a dangerous game country.

if you compare it with a 333 jeffery this is a very common rifle and it would be hard to find another pre war 9,3x64 again.

do you think the jeffery have the original stock? look here
