SG 435a PUC 1d Scarlet Watermark Block Cypher sideways in Post Office fresh unmounted mint condition.

Slightly trimmed perforations to upper margin on this booklet generated variety quite heavily reflected in offered price.

Though many try and sell sets on this and similar issues I am always more than happy to try and help out with single stamps and indeed see this as part of the service most dealers should offer to customers old and new.
