weapon identification help!

ok so my friend got this old rifle and im thinking its a kar98. but there are some insignia/engravings/emblems on the gun that ive never seen before. anyone got some answers? if you cant tell, its an upside down crescent moon with an islamic star/ star of david (?). the letters are: T C/ AS FA/ ANK ARA/ K. KALE/ 1943. thanks guys.

 

Sure is. Have one in my Mauser collection. Best 25 bucks I ever spent!

 

wait, 25 bucks!? is it really that cheap or did you just get an awesome deal? . does anybody know how i can find out if this gun was actually used in action or if i could find out exactly who used it or something like that? theres a few tally marks scratched into the side of the gun and i think it would be really cool to find out if they mark how many kills a soldier may have gotten.

 

thank you for the help. i actually looked up a few things after i posted my original question and i found out it was the turkish flag right after i asked it . THANK YOU though!!

 

I bought mine about 12-15 years ago and that was pretty much the going price on them then.
