Plates 169 - 182 were printed using the Wet method
Plates 169 and 170 had upper imprints and a band of type C lathework at the bottom

Plates 175 and 176 had type D1 lathework at the bottom instead of the normal type D.
This lathework is similar to type D with the addition of several millimeters of additional engraving at the top and the addition of a line at the top.
It is really rather common but it always incomplete and hence is easily mistaken for type B.

Collectors should note that the all plate pieces of the 1c Yellow are more rare then
the catalogue value of a single stamp would predict. In particular, plate pieces of
the later plates are almost impossible to find.
The Imperforate Issues
In late 1924 the Post Office released a few imperforate sheets of the 1c to collectors.
This was in response to complaints that a few of these stamps had been give out previously as favours.
The stamps made available to collectors include imprint pieces from plates 179 and 180 and items with type B lathework.
The type B lathework pieces are not associated with plates 179 and 180 since those plates had type D Inverted lathework.
In fact the type B lathework items must come from plates 11 or 12 of the coil plates.
This seems to be inconsistent since if complete sheets of plates 179 and 180 were released then there would
be a matching number of lathework items. Similarly, if complete sheets of the coil plates 11 and 12 were
released then there should be numereous upper blocks with the plate inscriptions.
However, there are only lathework examples. No upper plate inscriptions have ever been reported.
The only explanation that would seem to fit the known distribution of material would be that the Post Office
picked up a few panes of 100 after they had been separated from the sheets of 400 but before they were perforated.
It would appear that some of the panes were from the regular plates and some were from the coil plates.
There are a very few items known with type D Inverted lathework, possibly only enough for one or two panes.
It is probable that these represent the original favours.

There was an arrow in the upper margin of the full pane of 400 stamps
to show were the individual panes of 100 were to be severed vertically.

Lathework type D inverted, probably from plate 179 or 180
Some time in 1924 several sheets of the 1c coil stamps were given out as favours.
These sheets were wet printed from plates 11 and 12 and were Die I.
There was a band of type B lathework at the bottom.

As with all of the favours there was an outcry from collectors, and so
the Post Office made examples available to collectors.
However, by the time this occurred the Wet printing process had been replaced by the Dry process, and
Plates 11 and 12 had been replaced by plates 16 and 17 which were of Die II.
