Pol,
Nothing special mate, just where this particular rifle saw ownership after it was sold by the Commonwealth. Britain supplied No4's to more than 30 countries in the years subsequent to WW2 ... Turkey was one of many. A key indentifier for the Turk No4's is their penchant for adding that little post swivel to the upper band.
P.S The Op's rifle also has a Savage made safety ...
Cheers, Tiki.
