The badge shows a yellow cockerel with red comb and wattle on a black rectangular background. Yellow dots to the edges. Cockerel faces right.
The badge represents a link to the 40th Division of WWI which, from 1917, had a bantam cock on a white diamond.
Cole says that the bantam cock should have a red beak and legs and that the background should be royal blue.
There was no 40th Division in WW2 and this formation was formed in June 1949 in Hong Kong, with 26th Gurkha and 27th Infantry Brigades under command, 28th Infantry Brigade from the UK joining in October. Two battalions and some supporting troops were withdrawn from the Division to form 27th British Commonwealth Brigade in Korea between August and October 1950. The Division was disbanded in April 1952.
