Here we have what is known as the 'Cold Weather' or 'Flying Overall' Insignia for a Brigadier in the South African Air Force.

From a gander into Dudley Wall's Book "Starting Out"......Collecting South African Militaria. Page 77.....No. 17 shows what we are offering here.
"Quartermaster's Comment":- This pair is MINT.......A close look at the plastic Castle and the Star shows the emblems for the 'FOUR' Provinces of that time clearly depicted. Wall has this......'Cold Weather/ Flying Overalls'......insignia as worn from the mid 1980's through until 2002.
