This is a continuation to the posting in June 2011.
Despite the classification in the stamp catalogues, these were not strictly North Borneo stamps. In common with  the other JO stamps of Northern Borneo, they were issued for use throughout this region which was under the control of the Japanese Army. Kalimantan was under the control of the Japanese Navy. The confusion might have arisen due to the scenes depicted in the stamps which had been used in one form or another on previously issued North Borneo stamps.
The issue date was 29 April 1943 and they remained valid till the end of the war. They were printed in Batavia by G Kolff & co in sheets of 200 with numbers at the margin for each line. The numbers went from 1-10 as the original sheet of 200 was divided into 2 panes of 100 (10x10). On the left side the numbers are in ascending order going downwards with the reverse on the right margin as shown above.
Used stamps of this issue were normally postmarked at Kuching or Sibu as evident from surviving covers, the majority of which are philatelic in origin. There was probably difficulty in supplying the rest of the territory due to communication problems. Those stamps or covers with genuine Brunei or North Borneo JO cancellations should deservedly command a significant premium.

Air Mail hand stamp

A very clear airmail hand stamp from Jesselton dating from 2-3.6.1930. I think it was from Jesselton based on the shape of the propeller even though it is not an exact fit to the one in Proud's book. Similar hand stamps were used in Kudat, Lahad Datu, Sandakan and Tawau. The latter two, for whatever reason, are the most valuable.
These were used to mark mail carried on a series of well documented flights around North Borneo in June and July 1930. These North Borneo RAF survey flights of the coast were carried out by two Flying Boats of the 205 Squadron.
The majority of covers were philatelic but are nonetheless very sought after. They constituted a specialised area of collecting for North Borneo.
Update: Over the past 12 months, I have been able to examine a number of of covers posted from the various towns with the cachet. The conclusion is, after discussion with colleagues and despite what has been written, the same cachet or cachets were used on all the flights. I think there were one or possibly two handstamps which were carried on the planes themselves. It was likely that they were constructed locally with either rubber or a local hard wood. I favour the latter due to the clarity of the cancel above and also has to be durable enough to survive the war. Rubber would have degraded after a number of years.
I have yet to see a non philatelic cover from this series.

Somehow this 1930 Jesselton hand stamp survived the war. The post office in Jeselton was the only building in the area to remain intact. It was used specially to mark the first flight by Malayan Airways from Jesselton to Singapore via Labuan and Kuching. It took place on 7.6.1949. The covers were postmarked the previous day at Jesselton. The postal rate was 25c. The name of  Thomas Tai is not infrequently seen on philatelic covers of that period which were sent to Kuching. Apparently, he worked at the post office.
The old post office in Jesselton/Kota Kinabalu is situated on the northern end of Gaya Street is now the local tourist office.

I have included this nice philatelic item bought for very little money. It has an attractive fancy type airmail cancellation which can be found on some USA and Philippines covers. In addition to the airmail hand stamp, there is also a Houston Texas cancellation in red violet. It transited in Galveston on its way to Chicago.   

There is a series of these philatelic Java-Borneo airmail covers posted from Balikpapan. This one has the appropriate stamp.
