Osa would have bought hers 'off the rack' when outfitting the safari. This rifle was probably just sitting next to it, which was next to the next one etc ....

Remember, these were tools required to feed a camp staff of often 100+ souls. They had to be reliable and not much else. Any other attributes have been added with time as they enter the realm of 'sacred cows' of the Safari Industry.

Bloody good rifles none the less. Good buy.
