Tasmania - "Chalon Head" Issues

Subsequent supplies of the first three values of this series were printed in Tasmania on unwatermarked paper (1856 - 1857), and, from 1857 to 1869, on paper watermarked with a double-lined numeral (1 for the one penny stamp, 2 for the two pence, and 4 for the four pence).
Several printings of the penny stamp were in a distinctly brown shade.

In 1856, the colonies name was officially changed to Tasmania, and all new stamp designs subsequently incorporated that inscription. New stamps in denominations of 6 pence and one shilling were ordered from Perkins Bacon in 1857, and, as before initial supplies were printed in England and the stamps and plates sent out to Tasmania.
These stamps were printed on paper watermarked double lined numeral (6 and 12 respectively), and issued imperforate in 1858. The shades of the 6 pence varied most, ranging from a dull slate-grey to a reddish-mauve.

Originally, all the stamps issued by the Tasmanian Post Office were imperforate. As a service to their customers, several license stamp vendors began privately perforating and rouletting, the stamps they sold.
Chief amongst these was the stationary supplier J. Walch and Sons, of Hobart. This firm used perforating machines measuring 10 and 11.8. Another was R. Harris, of Launceston, using a machine measuring 12.5. Various other perforations and roulettes are known.
In later 1871, the Governement obtained its own perforating machine and subsequent supplies were issued perforated 11.4.
