These should be in stock by next week. These are from the early De La Rue 2013 printings with no printing date nor sheet number.
As with the original printings the colour cylinder is D2. The iridescent cylinder is again D1 - a different D1 to that used before, of course. So when comparing cylinder blocks, collectors (and dealers!) need to look carefully at the stamp as there will be several different D1 D1 D2 blocks.
