I just picked this rifle up off Gunbroker.
H. Mahillon Mauser in 9.3X62
Finish wise, its a little rough - some pitting and flecks of surface rust over much of the action and some of the barrel. Most of the barrel is in pretty good shape though.
Speaking of the barrel, it is very nice with an integral quarter rib and sling eye on the barrel step. Nice two leaf express sight in the rib and the bore is very strong.
It has a threaded trap grip cap which has an extra front sight blade in it - nice touch.

I'm thinking this is an FN action, right?

The wood is absolutely fantastic for a classic safari rifle!

I think I'm really going to like this rifle.
