Dollis Hill 2d Green AOP Wmk sideway (to the right)

The strip of 9 stamps shows horizontal cuts to the top and bottom perforations characteristic of stamps produced in coil format. It is not beyond reason that stamps in coil format were produced for experiments. Alternatively scrap paper with sideways watermark was supplied by Harrisons to the Dollis Hill team for use on their experiments.Ex Edward Klempka Author of the DOLLIS HILL FIND illustrated on page 39.
