20 October 2016 - 1st class deep scarlet Machin definitive from new retail booklet of 12, in new colour. Year code M16L, source code MTIL
, booklet has new font for text.
SG number U2968ea - new number for new shade.
In December 2016 further printings of the booklet were made on covers with new type of security printing on the backing paper, this we refer to as SBP2.§ Please note we have changed the number of the original printing (SBP) from 2936.6a to 2936a.6 - the basic stamp is a new colour and therefore has the suffix 'a' (2937 is already in use). This stamp with SBP2 is therefore changed from 2936.6b to 2936a.6a
This is expected to be another short-lived booklet as the next printing should have year code M17L.
