Here's a bandolier:
They hold 50 rounds in five pockets, each pocket has two five round chargers in it. The 1960's South African ones (as pictured above) were packed with a card insert between the two chargers, presumably to stop them rattling.
Here are some chargers (stripper clips)
The 1957 Radway Green ones we were firing today had no card packer. The British bandoliers I have are of much stronger fabric than the South African ones, although as they were a disposable item I doubt this really mattered. They had slightly different fastenings too. Here's a bandolier showing the strap arrangement:
It's been knotted to adjust the length.
Apparently the Australian ones had press-stud fastening and an adjustable strap. British ones I've seen have a brass or copper wire loop fastening, South African ones have a pressed brass tab.
The 37 large pouches were intended for Bren magazines in the main although of course you could stick extra kit in them.
I have a pair of these rifle pattern pouches that just hold chargers. Don't know what the idea was with these, they must have cost far more to make than the standard large '37 pouches!
