Stamps printed in new or changed colours were introduced in 1950-1951 to meet Universal Postal Union regulations. The 4d stamp was issued first in Oct 1950 due to an increase in the Foreign Letter Rate from 3d to 4d and (AH) rolls were issued in the same month (earlier rolls lettered (AH) had been discontinued in 1920). The ½d to 2½d were issued to coincide with the opening of the Festival of Britain on 3 May 1951. There was no change of colour for the 3d or 6d stamps, hence no (CJS) rolls are listed in New Colours.
Leaders for all rolls, other than buff ones, were in bright colours on white paper with a Harrison watermark, either upright or inverted across the leader, or along the leader on some (P) rolls. (Wilding (P) rolls have the watermark along the leader, but this issue exists both across and along.) Bright coloured leaders for endways delivery were perforated gauge 14.

Experimental rolls for vending machines in exposed places were introduced in Feb 1952 (EXP being an abbreviation of “exposed” rather than “experimental”). They were replace by (AA) and (AB) rolls when the smaller size was adopted in 1954.
