The 2nd class business sheet was reprinted on 04, 14 & 15/12/16 and appeared in January 2017.This new printing has the repeated text ROYAL MAIL on the backing paper beneath the stamps of a new type, with alternate pairs of lines of text inverted. The stamp is, of course, the same as the earlier M16L types.SG U2961
(also used for earlier years). (We previously numbered this as 2911Ba.6 in error)Comment: For some stamp (sources) the 2016 printings will exist in both forms. But the duplication is likely only in one year for each stamp source.
We expect that the M17L version will appear early in 2017, so making this M16L SBP2 version shortlived.
Also available, sheet tops from the 04/12/16 printing, numbers 4256641 or 645 - see separate listing.
