NB 1961 issue, overlooked but interesting

From the very old to the not so old, the North Borneo 1961 issue and its subsequent 1964 Sabah overprints are very much overlooked but does present some interesting possibilities. It was a breath of fresh air after the disastrous photogravure issues of 1950 and 1954. The designs were actually quite attractive, not classical but contemporary. 

There are a fair few interesting postmarks that comes with these stamps some of which are uncommon. And of course, I have already touched on the Bintang postmarks in October.

North Borneo stamps with Sabah Malaysia postmarks. They are not that easy to come by in the UK. Perhaps there are more at the place of origin.

More Sabah Malaysia cancellations. These Sabah Malaysia postmarks came into use some time in 1964 even though the Federation of Malaysia was formed in September 1963. It was not until 01.07.1965 when the Sabah overprinted stamps were available. Jesselton became Kota Kinabalu on September 30, 1968.
The 4c orange stamp has the interesting Jesselton postmark with a one line date which includes the the time, in this case 8:30am.

An airport postmark but unfortunately not from Sabah. I have been told it was from Singapore. I am not sure whether it was used there (airport paquebot?) or it could have been an arrival franking.
Update Singapore was part of Malaysia from 1963 to 1965. This stamp was probably used locally as stamps of the individual states were valid for use throughout  Malaysia.

A Singapore arrival postmark announcing the postal numbering system to facilitate delivery.
Update Again this stamp was legitimately used locally in Singapor.

No doubt my favourite of these group of stamps. These train mail stamps are much more difficult than some of the earlier ones. This is D9 used between 1955 and 1962. The D10 with the shortened month to 2 letters must be very rare as it was only used for a few months in 1962. The Railway TPO(Travelling Post Office) series of postmarks started in the second half of 1962. I may consider showing part 2 of my TPO collection as a Christmas treat.
