2nd swamp pattern
This pattern was used for quartershelters - both square and rhombus shaped.
Several variations of this pattern exist. According to Panzerwerk Post war zelts there are 4 variations:
Pre-1952 -> hard edges, no white
1952 -> added white, mostly covered solid and heavier rain strokes
1953 -> blurred edges, some white and slightly less heavy rain strokes. Maybe brighter colors (could be production variation).
1954 -> combines 1953 version with pre-1952's hard edges and lighter rain strokes.
This pattern was also used for paratroopers smocks - cut like the British WW2 Denison.
