The new tariff and Royal Mail Signed For stamps have arrived in Post Office branches on the day of issue, enabling collectors and dealers to get their first day covers with CDS postmarks.
But for those collecting date blocks, or simply recording printing dates there is a surprise, as these details are missing from both values that we have seen.
These strips are from the lower pane of the guttered sheet of 50. The sheet number and printing date would normally be in this margin.
Perhaps some exist with the date? I'm sure somebody out there will tell us - and send pictures. Thanks!
UPDATE 28 MARCH:
1. All reports so far indicate that the date & sheet number are absent on all stocks.
2. My postmaster told me today that Branches were told yesterday afternoon to stop selling these Royal Mail Signed For stamps and that they should not be sold until Tuesday 2 April. Tallents House subscribers will have received their 'first' announcement of these stamps: I've sent this image to Post Office and Royal Mail Stamps by twitter.
This explains one of our correspondent's experience at York where he was told that they would not be on sale until Tuesday (and they didn't have any anyway). Distribution seems to have been sporadic with rural sub-post offices receiving them but Norwich's main crown office (said they) had not.
Post-Easter update: As Brian reports in Comments, below, the instruction to postmaster was to hold back the Stationery associated with the new branding ie Royal Mail Signed For, not the stamps. My postmaster sheepishly admitted this today - and also said that they hadn't had any of the new stationery anyway!
