Items known:
18.11.1980 Göteborg to Jos (Nigeria)

18.11.1980. Air mail letter 15-20 grammes to Nigeria. Correct rate 200 öre + 40 öre/5 grammes = 360 öre. Shortpaid 170 öre. Due handstamp indicates deficiency 170 öre and foreign letter rate 200 öre. The Nigerian postage due should be 170/200 of the Nigerian foreign letter rate and a handeling fee but it is probably not correctly calculated on this item
