2nd class Post and Go Label used for immediate postings
When Post and Go Wincor-Nixdorf machines were introduced in 2008 they vended 'Faststamps' - stamps to take away and use later - and Post and Go Labels for immediate use. These were printed on labels with the ROYAL MAIL legend at the left, but no picture, no Machin Queen's head.
The replacement NCR machines introduced in 2014/15 used the Post and Go base stamps (pictorial and Machin) for this, instead of plain labels.
The labels are now becoming obsolete as the last Wincor-Nixdorf machine will probably be replaced by March 2015.
