These images are from eBay listings and show stamps from the machine at Nailsea, Bristol:
Thanks to Doug for this collectors set of 6 x 1st Spring Blooms from the Eastcheap NCR machine.
Royal Mail are unlikely to produce any 2013 or earlier special sets on NCR-size rolls, although the Union Flag should appear in due course. The Robin may appear, but the final 2014 set is Winter Greenery which may be used instead of the Robin. No announcements have yet been made.
And on that subject, I do not expect there to be any announcement from Royal Mail about the introduction of Spring Blooms to the NCR machines: the stamps were issued in February. Royal Mail would have anticipated the extensive roll-out by Post Office Ltd of the NCR machines and accordingly ordered part of the printing to be on NCR-size rolls.
By request, this is the link to the stamps that I found on eBay: http://tinyurl.com/k4ht4wo
Finding things on eBay is very easy: simply enter key words (I used flowers ncr in the Stamps category.)
I'll show other examples here as I get them:
