I'm assuming all five photos belong together as they do appear to be the same rifle. The first three are labelled .425 which I am guessing was a photo titling error.

Lovely well made custom Mauser takedown in 9.3x62.

Personally I do not like the "blue" bolt at all, and the stag or elk bull's head could be better executed, and it it was me, the gold is too much, but that's just me. But the rifle, case etc is otherwise so well made, I'm sure its owner will greatky treasure it.
