Term applied to the trial separations carried out on the G.B. Penny Red between 1848 and 1850 by Henry Archer, inventor of the first practical perforating machine. Some of these were rouletted 12, others perf 16. These trials were undertaken privately but with the consent of the Post Office, the stamps being distributed in the normal way. They were followed by Government trial perforations. In June 1853 Archer was awarded £4,000 by the Treasury for his machine and his patent rights and from the beginning of the following year all British stamps (except the 6d. embossed) were perforated.
