M41/B Mauser Aus

Seems there is a supposed M41/B in Australia for sale that needless to say I'm really interested in, but looking at the scope and scope mount numbers I am unsure that they match each other, or even match the rifle.

Firstly the scope number seems fine, but the mount number on the side has been crossed out and replaced below with a higher number, but the number on the scope matches a third set of numbers printed into the top of the mount.

Here are some pictures the wonderful owner has sent me with the numbers I am unsure of.

Pictures are not working for me

It seems to have buggered up and I'm a little new. Slowly getting it sorted though.
