Looks quite nice mate,
You dont see much S.African surplus about.. A piece of history from back in the apartheid days. Wonder what else is about??
There is plenty South African kit around, they still use those M83 Pattern packs.
It is quite heavy but tough as nails like all the Bush war era kit.
A better pack to look out for is the Batteleur 90 Pathfinder pack that our paras use, has a lighter aluminium adjustable butterfly frame and can be used with or without the frame and has a few more pouches.
They are becoming more and more scarce because the guys in the military prefer it over their issued M83 packs.
Will post some pics later.
