The first Machins with a 2012 year code have been found - the retail book of 12 x 2nd class, with code M12L MTIL.
When we get stocks we will keep these for regular customers and add them to our online shop.
(sorry, we still don't have any! 10 Feb 2012)
Thanks to RP for passing on this from JB.
Thanks also to Kevin who reports that the booklets have a packing date of 03/01/12 - and they've managed to get them into Post Offices already. This is Swindon-delivered stock, not something sent out from Royal Mail Direct to a corner shop or supermarket! That doesn't mean, of course, that Swindon might not have 2011 stock under the 2012. It does make me wonder how big the print run was for the 2011 12 x 2nd with FSC advert issued only at the end of last October.
Let us know if you find any of the 2012 stamps! Booklets from non-post office outlets seem to be the most likely finds, but 12 x 1st are unlikely as the uncoded Jubilee stamps are in use.
