Showing a bit more Labuan. These are from part a sheet of D11 cancellations that I showed at our SSS meeting during Singapore 2015 World Stamp Exhibition. Usage of D11 (July 1930-November 1941) was when Labuan was part of the Straits Settlements.
Nice pair on piece as well as 2 different stamps which were alongside each other originally on a cover. D11 is very similar to D10 but has an actual time instead of the time code.
