Kenya Uganda Tanganyika: No Air Letter Service to Switzerland in 1946

Air letter form sent from KAMPALA (17 JAN 46) to Geneva, Switzerland (30. 1. 46).

The acceptance of air letters in international mail was subject to bilateral agreements between postal authorities, before aerogrammes were established as a standard UPU mail item category on July 1, 1953.

At the time of posting, air letter service between KUT and Switzerland was not yet established. „T“ handstamp applied in the country of origin. The air letter was treated as a short paid ordinary air mail letter, for which the applicable rate was 1 s 30 cent. Hence, the air letter was short paid 80 cent.

The Swiss postal authorities calculated the postage due as follows:

Swiss international letter rate / Foreign country international letter rate x deficiency x 2

The Swiss foreign letter rate was 30 Rappen, the KUT foreign letter rate was 30 cent, which gives a postage due of 160 Rappen. The payment of the postage due is documented by four postage due stamps with a total value of 160 Rappen.
