Belgian Brushstroke / Moon and Balls Camo on Same Hood

I found these today in a surplus store.

They had a bunch of regular Belgian Brushstroke hoods for the smock, and one hood made entirely from moon and balls camo.

I found these mixed in with the hoods:



They appear to have Brushstroke fabric on the center part but moon and balls fabric on the side parts.

How common is it for fabric to be mixed and matched like this? It looks way too well done to be a field repair.

It's not too common to see them together on the same piece, but it's not surprising either. Especially for something like a hood. There was about 2 years of overlap in production of M&B and Brush so plenty of time for cloth to get swapped around. Not necessarily by accident either.

Over the years I've had several items with both patterns on them, eg brush trousers with m&b knee reinforcements etc
