India: Short Paid Aerogramme

This 6 AS aerogramme (Wiegand #5) was sent from Calcutta to Sweden on April 27, 1953. Endorsed "T" to indicate that the aerogramme was short paid.

Since March 24, 1953 the aerogramme rate to Zone III (Europe) countries was 10 AS. Hence, the aerogramme was short paid 4 AS.

As the Indian foreign letter rate was 4 AS 6 Pies at that time, double the deficiency (8 AS) was converted into 35.55 UPU centimes (at a rate of 4 AS 6 Pies = 20 UPU) ctms.

Sweden seems to have converted UPU ctms at par, yielding a postage due of 35 Öre which is endorsed on the "Lösen" postage due label.
