Type 1 ([Fig. 24]). Office Numbers from 1 to 56, and 100. Used also at Cape Town base with initials BO (Base Office) and an asterisk (sometimes omitted) in lieu of the office number. Also at sub-base offices with larger office numerals 1 to 9.
Type 2 ([Figs. 25, 26]). Commonly without the year being noted, as in the first illustration but also found with the year
as in the second illustration of this mark. It has been largely supposed, but without much, if any, foundation that these year-less marks originated in Ladysmith during the siege, but little correspondence can have been passed out of the town during that period, and the origin of many of these marks is known not to have been Ladysmith.
Type 3 ([Fig. 27]). Used in sub-offices supplementary to type 1, found stamped in blue-green as well as in black. Office numbers 41-60.
