Vietnamese Air Force ‐ 1953
This cover was sent from the sergeant in charge of personnel at Soc Trang Air Base southeast of Can Tho on 24 November 1953. The fledgling Vietnamese Air Force was still under French command at this time.
On the red unit cachet we once again have an example the French abbreviation "S.P." Four‐digit Sector Postal hand stamps were in use for only a couple of years.
Note the sender used the abbreviation "KBC" in the return address.
