This “Rhubarb” camouflage pattern was mainly used by Eastern Bloc-aligned guerillas in Africa, most notably SWAPO in Namibia, and has no known specific origin. It could be from Libya, Romania (source: http://www.newrhodesian.ca/viewtopic.php?p=7891#p7891), or former Yugoslavia (see usage photo below).  The set depicted on this page was captured by same 32 Battalion officer as Cuban shirt.

Shirt:

Standard 2-pocket Cuban style cut.

Button:

Tag:

No other markings on item.

Trousers:

Somewhat rough twill, feels somewhat slippery.  Pants made of heavier fabric than shirt.
