I think this is the same rifle.

A Greek Military action I think also. The lack of the bolt lock spring the first thing that caught my eye.
If it's the same rifle, the close ups shows gaps in the inletting (as do the GunInterN pics if you look closely), engraving of average quality or less.
The pad probably a later addition. Maybe to replace an old pad that had deteriorated or just because someone needed a pad.

Not a bad rifle but for the price I think you could find a factory original Steyr pre War2 commercial product.
