The large "Nyasa" or keyplate design was used by several colonies for their high value revenue stamps. In place of "Postage" and "Revenue" in the side panels of the stamps valid for postage, "Revenue" was repeated on both sides. This format for revenue-only stamps was introduced late in the reign of KGV and used for a late printing in 1935 of the $25 Straits Settlements keytype and the more familiar Bermuda 12/6 revenue produced in 1936. This design was adopted by Ceylon and Nyasaland printed in sheets of 60,
and by the Malayan area - Straits Settlements, BMA Malaya, Malacca, Penang and Singapore-in sheets of 50.
A variant incorporating the word "Kodi" in the top panel was used by both Kenya and Tanganyika; while Uganda replaced "Kodi" with its English language equivalent "Poll Tax". These were produced in sheets of 100. Unlike the 50/60 sheet layout, the printed sheets were arranged in four panes of 25, separated by pillar type horizontal and vertical interpanneau margins.
