These pouches are made from similar canvas material as British and Belgian Pattern 37 webbing. They appear to have been made for the commercial export market and were mainly used in the 1960’s, particularly in Southeast Asia (Laos, Thailand, Vietnam)[1] as well as in Africa (Congo[2], Rhodesia[3]).
