Civil Adress / Not Forces Mail

This aerogramme (Greiner no. 55) was sent from Gloucestershire  (29 OCT 1973), to Shreveport, U.S. The aerogramme is h/s "Civil Address - / Not Forces Mail".

Most likely, the aerogramme was fed into the BFPO network but sorted out because the addressee was a civilian. The aerogramme, then, was transferred to the Royal Mail post office in Gloucestershire.

Since September 10, 1973 the aerogramme rate was 6 d, so the aerogramme was short paid 1 d and should have been taxed accordingly. Apparently, the postage due went unnoticed.
