"108" Postage due charge mark on unpaid letter postmarked Calcutta (India) August 9th 1859 and sent via Suez, Marseille, Paris and Hamburg to Carlskrona. The sender of this letter was a swedish seaman (Gustaf Carlström) in the Indian navy and his commanding officer has signed the envelope. This procedure was used by non-commissioned officers, seamen and soldiers in India to get lower postage for private letters, but this has not affected the postage for this letter. The rate to France was 80 ctms, 30 ctms unpaid, French-swedish rate was 100 ctms = 150 ctms, in turn translated to 108 öre.
