The postcard below, from Cheddar to Watford in 1932, was posted without a stamp and incurred 2d postage due. The "2 D / TO PAY / 134A" charge mark was applied in Bristol - this charge mark was previously only known from 1934 to 1948 in red and in 1948 in black.
The envelope below was also sent without a stamp from Glastonbury and Street to near Canterbury in 1970.
The envelope below from Wincanton to Bourton, Bath was sent with a Revenue rather than a Postage Stamp in July 1881.
The passing of the Customs and Inland Revenue
Act 1881 merged the systems for postal and fiscal accounting. The act
explicitly stated that "stamp duties of one penny may be denoted by
postage stamps, and vice versa". From 1st June 1881, unused, existing 1d Inland Revenue stamps (which were previously meant only for taxes, receipts, and documents) became legally authorized for use as regular postage on mail. These are known as postal fiscals. The 1d lilac, issued on 12th July 1881 was inscribed "Postage and Inland Revenue" and was valid for both sending a letter or paying a tax duty.
