This is a very rare brown pattern M31 Splittertarn Zeltbahn.
It is stamped/dated 1942 on the underside.
One side is brown splittertarn camo, the other side green.
From what i can see almost all buttons are present and there is only minor wear and tear. I’d rate it to be in good condition.
These brown Zeltbahn’s are very hard to find and were only around 1942 in use for a short time.
