4 Annas Chabua; NCO Club

APO 629 was the Army Post Office designation for Chabua, Assam, in northeastern India — the eastern terminus of the Hump airlift route over the Himalayas into China. The NCO Club scrip issued there was purely internal currency, usable only within the enlisted men's club facilities on base. These pieces were printed locally in small quantities, almost certainly without any central oversight, which accounts for the considerable variation in printing quality found across the series.

Pink paper was a deliberate color-coding choice, distinguishing this denomination from others in circulation at the same installation. Few survived the war — most were redeemed, discarded, or lost when the base was demobilized after 1945.
