All items unmounted mint blocks of six, perforation type A, unless otherwise stated.
M.m. items are usually mounted on top one or two stamps, though I state this only
for guidance and not as a guarantee. Plate flaws present indicated by appropriate
specialised catalogue number (from S.G. Great Britain Specialised Catalogue, Volume
3, 11th. Edition).
* Denotes Minor Constant Flaw on one stamp in block. Phosphor blocks are TWO BAND
unless stated.
