Thanks for the tips, Mikey.
A buddy found some links for me that provide serial numbers and info on Turkish Mausers.
Unsurprisingly mine is 1938-manufacture 1903 Mauser.
The raised stripper clip cut and a couple of other things show this.
It should turn out ideal for 7x57.
Now I just need to get a trigger/safety to replace the military one, drill and tap for scope mounts, have the bolt handle turned and get the bbl screwed on and the whole thing reblued.
I was going to go without an after market safety but when I hunt deer I often walk with the rifle cocked and the safety on so I can react quickly should a target present itself and it would be silly to penny pinch a few dollars and have to put up with that inconvenience.
I'm not sure which stock I'll get yet but probably either the Classic or the Prairie Hunter.
I like the Royal Jackaranda laminate but it's probably not ideal for camoflague.
I'll probably try and get the Forest Camoflague.
The $100 spending limit on International orders limits my choice anyway.
