In 1863 the postage rate to reach the UK was set at 6 annas 8 pies but there was no adhesive to meet the need. Here is one expedient, from Kolkata, overprinting stamps intended for fiscal use, here the six annas Foreign Bill design. The top and bottom panels have been cut off completely. Of the two settings of overprint, the lower version exists in 20 different types and a difference is clear within the pair displayed.
A rare inverted overprint
Service overprints appeared in 1866 but soon fell short of demand. Agin, in Kolkata, the Post Office had to overprint stamps intended for fiscal use, here the two Rupee Foreign Bill design. The top and bottom panels have again been cut off.
The half anna issue, this time using the 'Receipt Bill or Draft’ stamp of 1861, and bearing a double overprint
As last, the eight annas value
This is an officially sponsored reprint, from 1884-5, note the larger font and new shade.
And this unused fiscal bears a forged overprint and postmark. Beware.
In 1898, postage for registered newspapers was cut to three pies but there was no stamp to meet that need. Here are two examples of the resulting surcharge, both to some extent doubled. See the design that was to come.
