It's the start of 2014 and we thought we knew about all of the stamps were issued - or discovered - in 2013, and they included some surprise 2012 printings.
In July last we reported the fact that the 2012 2nd class coil (which had been available mint for a while) had now been found used on a bulk mailing.
But now a new version of the 2nd class MRIL has been discovered in kiloware.
UPDATE 28 JAN 14
We understand that this and the 1st class red were printed by Walsall Security Printers in the second half of 2012. (The 1st class distributed by Royal Mail Tallents House were MA12, from Enschede.)
This clearly shows M12L - MRIL. We will be interested to hear of any further findings, especially on whole cover, or enough to show the source, so that we can all look out for them!
UPDATE 6 February 2014
Thanks to John for sending this cover from Christian Aid. You can't see the iridescent overprint, but John assures me that it is the new M12L MRIL
UPDATE 13 February 2014
Another example has been sent, from Queen Elizabeth's Foundation for Disabled People. Thanks to 'Boweevil' for this.
UPDATE 14 April 2014
Closer to home, a further example has now been received from the British Heart Foundation, with the same postmark as the Christian Aid one. The return address is Melksham SN12 6WF
