Although not listed specifically by Unitrade, the stamps of this issue, like the previous War and Peace Issues exist with several different paper and gum types. In terms of paper so far I have been able to ascertain that there are five basic types:

(1) A thin, horizontal ribbed vertical wove paper. The strength of the ribbing varies from weak to very strong.
(2) A thicker medium horizontal ribbed vertical wove paper.
(3) A horizontal wove paper with no mesh, used on the coils.
(4) A vertical wove paper, with horizontal ribbing, used on later printings of the coils.
(5) A horizontal wove paper, with vertcal ribbing, used on some printings of the coils.

The gum found on these issues includes:

(1) Cream with a semi-gloss sheen.
(2) Cream with a satin sheen.
(3) Yellowish cream with a semi-gloss sheen.
(4) Deep yellowish cream with a semi-gloss sheen.
(5) Streaky cream with a satin sheen.
(6) Streaky cream with a semi-gloss sheen.
(7) Cream with a glossy sheen.

These differences are useful because they give clues as to the order of the printings, and an individual stamp can be assigned to an approximate year based on these characteristics. For example, the late printings will share the same characteristics as the early printings of the 1953 Karsh Issue. For this issue, that would appear to be the strongly ribbed papers, and those papers that are thicker, as well as the gums with a semi-gloss sheens. These would appear to be from between 1950 and 1951. The gum on this issue often has natural spots that can resemble small blemishes. This is particularly true with the glossy gum. These spots are NOT gum disturbances, but are natural blemishes that arise during the gumming process.

The plate blocks show plate dots in various postions on the lower left, lower right and occasionally the upper right blocks. Studies of Elizabethan material have concluded that these dots signal different printings. In additon, on the lower left blocks only, there are different spacings between the plate number and No., as well as between the numbers of the print order number. I refer to narrow, intermediate and wide spacings in my descriptions. Narrow spacing has the numbers or letters very close together. A small space between the letters or numbers is intermediate spacing, and finally a space of more than 2-3 mm is wide spacing.
