This is also a flaw that has been known since the 1970s but somehow not deserved a listing. The zero in 10 was damaged on the printing plate to give rise to this constant flaw in the transfer B printing. It is found on stamp 46 on a sheet of 50. It was used with a 17 or 19 bar Sandakan cancellation and also has the China Borneo Co Ltd company chop on 14 SEP 91. This 6c on 10c surcharged adhesive was issued in 1891.
This is again from the same 1891 issue and a has a clear 17 or 19 bar cancellation. These 2 bar cancellations have very similar dimensions and are probably from the same handstamp with the small end bars of the 19 bar cancel not showing clearly or fallen off/damaged with repeated use. I am very curious about the additional cancel in violet with an interesting shape, most certainly another company chop.
The high values genuinely used with a bar cancel are rather uncommon. This 1888 50c stamp has a part 17 bar cancel. There are 9 bars visible here. The 17/19 bar cancellation is longer and wider than the 14 bar CTO cancel. Some of the high values have genuinely used 14 bar cancellations but it would be impossible to tell on a lone stamp.
This 1909 adhesive has the Labuan D10 cancel with code C with a date of 8 JY 1925. By this time, Labuan was part of Straits Settlements. This therefore represents paquebot use for mail posted on sea craft on its way to Labuan. By the way, we are down to one solitary surviving middle aged female rhino in North Borneo/Sabah. What a complete mess!
Update Our only rhino died on 23 November. No more rhinos in Sabah and a few left in Indonesian Borneo, Kalimantan. But lots of forest burns there.
This is the same situation here but we have a Labuan D10 code E and dated 3 JN 1929. Code Es are elusive but are disproportionally found more on North Borneo stamps without a clear explanation yet.
