After the end of the Second World War, the Brunei government which was then the British Military Administration (BMA) used stamps of Sarawak and North Borneo in Brunei. The only difference between the original stamps and that of BMA was that the stamps were marked BMA in black or red. I wanted to buy a whole set of Sarawak BMA. One day I got an offer for the above set. I did not hesitate and quickly grabbed this.
