31 March Cylinder Blocks - of 6, and not self-adhesive!

Despite apparent evidence to the contrary we can confirm that the Machin definitive and country definitive stamps are printed in sheets of 200 on conventionally-gummed paper, and have cylinder numbers adjacent to row 18 as they always have been.



For speed and space I have only scanned one of each - apart from the position of the 'blob' in the grid (can two squares be a grid?) - all the sheets are the same, the number of cylinders being the same as in previous years.
