This is the Romanian Army 1980's Infantry Assault Pack. Made with heave cotton material, and leather.
In the pictures, I have an over night kit packed, including summer weight sleeping bag. So, this pack is capable of carrying all one needs for a 24 hour or more camping trip in the warmer months.
Very well designed and constructed.
From the inside this is a simple thing: it has one large main space closed with a piece of string. Dimensions from seam to seam about 30-35 x 40 x 26 cm / (12" - 14" x 15.5" x 10"). The pack is wider from the bottom than on the top.
*** Axe and canteen not included
