Perforations on all Newfoundland stamps have been very carefully checked using an Instant perforation gauge, which measures accurately to the nearest .05 of a hole. Unitrade does state the number of perforation heads used by Whitehead and Morris to print the issues from the 1911 Royal Family Issue up to the Publicity Issue, but it would appear from a study of the stamps that a considerable amount of variation in the perforations on the issues printed by them does indeed exist. The later issues printed by Perkins Bacon also exhibit The Walsh and Butte Specialized Newfoundland Catalogue lists these variations, but does not price them, as far as I know. So, we have valued them using the basic Unitrade prices.
