After being relatively inactive in stamps for about 2 months, I am now back into the usual stamps hunting. The latest addition to my collection are these 8 covers with the 3-line post-war cancels of Sandakan and Brunei. These postmarks were supplied by the New Straits, Singapore after the war and thus would usually appear on the BMA stamps, commonly from 1945-1946.
In North Borneo, there are postmarks for Jesselton, Tenom, Tawao, Sandakan, Lahad Datu, Labuan, Kudat and Beaufort. The Jesselton mark is only for proof strike and not seen postally used. The postmark from Beaufort and Tawao are probably the rarer ones among these. The Labuan postmark on the other hand has a morse code for "B.M.A" which is relatively unique among the others.
The 3-line postmarks were also produced for use in Brunei and Sarawak. For Brunei, there are 4 varieties of postmarks from the two towns - Brunei and Kuala Belait. In Sarawak there are postmarks produced for Sibu, Marudi, Bintulu and Lawas. The Lawas postmark has only 2 lines.
