Single Pane 240on
Chronologically, the 1d black was first printed by PB in 1853 and delivered to the colony the following year. For the next few years, it, and the locally printed lithographs were issued. In 1860, there was a single small colonial printing of just-made higher denomination PB plates, at which point all plates and swan wmk paper were returned to London to have subsequent printings and perforations done by PB.
1861 Intermediate, clean cut, Rough, and DLR14
Single Pane 120on 'half' plates
The Perkins Bacon Period only survived for two years, with a shoddy attempt by PB to use a worn out Perf14..16 machine.
There were two printings:
The four perf categories are:
Intermediate Perf14..16: First Printing only
All values were done on the perforator in it's 'shoddy' state.
Somerset Perfs: First Printing only
These are clearly identifiable as simple perf 14 and in a reasonable state.
PB asked Somerset House to do the perforating. They refused to touch the 6d and 1/- as too uneven to bother with, but, while managing to destroy over half of this printing in the attempt, they did manage to deliver quantities of 1d, 2d, and 4d.
Clean Cut Perf14..16:First Printing only
Having little choice in the matter because of DLR's previous refusal, by Jan 10 PB had overhauled their perforator and perfed the 6d, 1/- and remainder of 2d. The perforation is distinguishable as have cleanly cut holes.
It is negotiable how 'clean cut' the clean cut perf holes actually are, progressing back to the intermediate type.
Very rough perf14..16: 2nd printing only
It took little time at all for the perforator to deteriorate alarmingly into a super shoddy horrible rip and tear state of perforation. While there are, of course, stamps that would show progressive deterioration firstly into an intermediate state, they are all on this fresh paper and all, clearly, not clean cut.
Of course, all these differences are collectible as examples. But, they are, after all, damaged stamps of inferior appearance. How much time and wallet you want to spend on them is in the eye of the beholder. They should be priced as a percentages of good copies rather than varieties in their own right.
At the end of the 2nd printing, the Crown Agents had had enough. All subsequent printings AND perforating was done by DLR
The original intention was to use up the original swan paper in colonial printings of the plates. To that end, it was separated into bundles for the various denominations and cut in half, where appropriate, for 120on plates.
The back of some sheets had hand stamps applied to indicate what denomination the sheaves were intended for,
However, ultimately, after one small printing, the remaining paper was returned with the plates, and Perkins Bacon recorded the amounts available for printing, in contrast to the fairyland that Helmich requested.
Approximately half the sheets printed were perforated so badly, they were destroyed
