Machine Cancellations of Kuala Lumpur

I think in the whole Malaysia, the mail centre of Kuala Lumpur is the busiest one in handling the mail. It is not too surprise to know that the Kuala Lumpur mail centre has many cancellation machines. So far from my own observation/collection, ten cancellation machines are in used in the mail centre. I have recorded cancellation from machines number 1 to 9, however, I have not found cancellation from machine number 7. For machines number 1 and 3, two types of postmark are available - one-circle and two-circle. It is noted that machines number 1 and 3 are the most used ones for handling most of the mail. Cancellations from other machines number are considered "rare".
