2 Annas Chabua; NCO Club

APO 629 was the Army Post Office designation for Chabua, Assam, in northeastern India — one of the main staging bases for the Air Transport Command's operations over the Hump into China. The N.C.O. Club scrip was a purely internal medium, issued to keep cash within the club's economy and prevent leakage into local markets or black market exchange. These small-denomination chits were never intended to survive the war.

The "Northern ASAC" designation — Air Service Area Command — dates the issuing authority to the reorganization period of 1944, which may help narrow the actual print window despite the broad 1942–1945 attribution.
