Key & Duty. Comb14
This new value was invoiced and issued at the same time as the 2½d on 1st May 1892. It covered the double Overseas Letter Rate and the Inland and Colonial Registered Letter Rate. Limited use values such as this one had a No. 1 key-plate of 120 and a duty-plate of 60, duty plate doubled in February 1896
Bistre with reddish brown duty.
It is even more surprising that permission was given to double the duty plate and print two more deliveries close together. As it turned out there were enough olive-bistre stamps to last to about New Year 1906 - and then, the PMG was even very lucky because he could not have foreseen that demand by 1904 would increase 6 fold reaching 185,000.
line perf 12.4 or 11 in equal numbers. line perf because the 120on plate 2x60 did not fit the 240on comb perforator.
these printings occurred on the only non-replaced DLR key&duty plate.
