Wing-margins
Wing-margin stamps occur on the surface-printed stamps
1855-80. For the 3d, 6d, 9d, 10d, 1s or 2s stamps with watermark emblem or
spray the sheet is arranged in 12 panes of twenty stamps forming a sheet of 240
stamps, stamps with D, E, H or I in the SE corner will have a wing-margin. That
is 80 stamps out of 240 or one third will have wing-margins. With the
introduction of the Imperial Crown watermark in 1880 (SG 157) there are no
wing-margins.
For the 4d
and 8d garter
series the plate is in 4 panes of 60 stamps (10 rows of six) and thus letters F
and G would be wing-margins, that is 40 out of 240.
The 2½d
stamp (plates 1-20) had two panes of 96 stamps one above the other and no
wing-margins.
With the crown watermark there were
two panes of
120 stamps (ten rows by twelve) and no wing-margins
