Labuan stamps with Brooketon cancellation

Brooketon was a part of Brunei which was administered by Sarawak after they took over the concession for mining coal from William Clark Cowie in 1888. Sarawak stamps with Brooketon are not uncommon but they tend to command a premium due to the popularity of this postmark. It can also be found on adhesives of Labuan, Brunei and North Borneo with the latter two quite difficult to acquire. The ones on Labuan are not easy but somehow over the past 12 months I have managed to find two. I call this the "London Bus" effect. They do not arrive as expected but when they do, it is usually in twos or threes.

Despite the lower one having a a full strike of 4 MAR 03, I still prefer the upper example which somehow looks a lot better. There are so many Sarawak stamps with this Brooketon cancellation but strangely no cover so far I know. The nearest item to postal history was a card sent from Brooketon in June 1907 franked by a Brunei stamp but somehow received no Brooketon cancellation. It went through Labuan and Singapore on its way to London. The Brunei adhesive was uncancelled and invalidated. 

The likelihood was most of these Brooketon items were cancelled by favour even though some mail from the south western part of North Borneo and possibly north Sarawak and Labuan went through Brooketon. This was due to the more frequent communication between the mining company and Kuching. And then the mail was carried onwards to Singapore. So were some of these transit cancellations?

This is an aerial U S Navy photo on the pre-invasion bombardment of Brooketon on 9 June 1945 before the troops of the Australian 9th division landed 2 days later supported the U S 7th Fleet and Australian warships. Six 7th Fleet Venturas and eight Army Lightings were used. This picture shows the napalm drop. Apparently 95 percent of the Japanese base was destroyed. No wonder by the time the Australian troops landed, the Japanese had fled. 

Labuan D8 time codes A to E

For a long time, no one commented accurately on what these codes signify. By the time this D8 cancellation came into usage between 1910 and 1913, Labuan had already joined  the Straits Settlements in January 1907. Similar letter codes were seen in the Straits cancellations and these were time codes but whether they were used accurately is opened to debate. Logically code A would represent the earliest time period in the day and code E the latest. Code E is difficult to find and it may have been that it was used during a quiet late period, for instance when a ship arrived during the night. 

Time codes A & B on Straits stamps. This postmark can also be found on Brunei or North Borneo adhesives.

It is not common to find this cancellation on a Brunei stamp. We have the time code C here. Its usage would represent paquebot use or a transit cancel. The bulk of mail from Brunei went through Labuan during this period as there were regular ships plying the route between Singapore and Labuan.  

This is code D on a pair of of North Borneo stamps and probably represented paquebot mail from the south western part of North Borneo near to Labuan and would have been more efficient than going through the GPO at Jesselton. It could also be possibly an an arrival or transit cancel.

Time code E is quite difficult to obtain and probably even more unusual to be seen on a pair of North Borneo stamps. Were both these pairs of 4c adhesives used for books or printed matter for an item weighing 8oz?
