These smocks were produced immediately after the war, perhaps under a British contract (pending verification), to outfit Belgium’s paracommandos and were used immediately before the Moon and Balls and Brushstroke uniforms. They feature a hand-painted, grid-like camouflage pattern. Although clearly based on the British Denison Smock, the upper pockets are straighter, a feature that would carry over to some Moon and Balls smocks.

Sample 1:

The knit cuffs are a tailor modification. Newey snaps. 

The half-zip length fly opening is closed by buttons (no zipper) that are similar to those on British denim battledress utlities.
