I thought the left side of the belt also had small pouches like the ones posted above, but this comparison pic shows that the brass closure stud is quite central to the pouches, and they appear to be double the length of the small `Spanish pouch on there right side:
On checking the 'Move Along' with the two right hand guards, it looks like he does not have any MP40 pouches on his belt, and has this 3 pouch unit on his left side...just need to source it now!! I thought he had the small Spanish pouch to the right and the MP40 on the left, but this image tells otherwise!
