1955 – Transitional Military Postmarks
The cancels depicted here were taken from a single correspondence sent from a Transportation unit at KBC 4317/A in Dinh Tuong province. They illustrate the logical progression of postmarks in mid‐1955 starting with a typical French POSTE AUX ARMEES cancel, transitioning through the provisional QUAN‐BUU 7 marking, and ending with an official Vietnamese QUAN‐BUU 7 postmark.
The numeral “7” indicates the Quan Buu Cuc, or military post office that serviced the military region. QUAN‐BUU postmarks are reported with numerals 1‐8. The practice of including a numeral was fairly short‐lived although covers are known through 1959 and even one usage reported as late as 1972.
