D34 1937-8 Postage Due Watermark G VI R 2/6d Purple on Yellow sheet marginal in Post Office fresh unmounted mint condition.

Really advantageous to have marginal copies on all of these postage due issues where it makes confirmation of the watermark and hence issue and price that much simpler if you don't have likes of a Signoscope to check.


Like every stamp I sell this has been fully checked and confirmed by myself as correctly identified and described, not just removed from album where it was listed as such.
