June 2015 - 1st class red Machin definitive from retail booklet of 12, year code M15L, source code MTIL
First reported June 2015 in supplies were not generally available until October. This seems to have been partly due to stocks being built up by the printers before the relocation to a new print works. Some packs of 50 have been reported as having a mix of M14L and M15L stock, with many April dated packs having M14L. Our M15L stock came from earlier packs, wrapped 30/03/2015.
SG number U2968e (has been used for other years).
