Portugal

Steyr Kropatchek

Sling as used on the Enfields from the British
The leather Enfield sling was also used as they had the Enfield before WWII

904/39 Portugese 8mm with correct sling.  Buckle is the same as the Steyr sling
above but it has a tie instead of the button.  This is not a field modification,
slings were made this way.

A little better pic of the buckle and tie
