It's a model 1600 Std, built in 1956, it's a European model.
The 1600, with 520mm barrels, ARE the "carbine" or "Lightwieight", while the "common" 600mm are named 1640.
There is a lot of confusion created by using the "1600" denomination as a common name for the HVA Improved Mauser.
The models should be devided like that ;
1600 = 520mm barrels
1640 = 600mm barrels, for which we add the "Husky" having a 560mm barrel
1651 = 660mm barrels, 358 Norma Magnum
