The 1st class gold coded MRIL MA12 from self-adhesive coils of 10,000 intended for bulk mailing houses has been discovered on a mailshot from Barclaycard - not a statement, but a circular. Be sure to check your incoming post and any kiloware carefully, as codes are more difficult to see on the 1st class stamps - and they aren't often used for mailshots.
These are now available - order yours here.
Also new for 2013
The 2nd class large booklet of 4 with MA13 code has been reported from the Midlands.
And, just a couple of days later the 2nd large MA13 from business sheets printed 03/03/13 has been reported.
We don't have any supplies or pictures of these. We'll add the pictures here and the links to our stock when we have it.
