The number plates were cast in brass, in a horizontal rectangular format with radiused corners. The size was about 18in x 10in and a raised ½in edge surrounded the plate. The plates were mounted on the tank sides level with the front of the cab. The plates of the first BNCR number series (Nos. 69 and 70) which was current to 1897 contained polished, raised, numbers with prominent serifs. The BNCR 1897 renumbering introduced a series of plates which had "BNCR" in small block capitals above the digits. The BNCR style of plates was used throughout both MR and LMS days. The MR (NCC) renumbering of 12/102 and 113/101, and numbering of 103 and 104, gave these engines plates with digits alone, but otherwise they were similar to the earlier series, and this principle was maintained in the last renumbering to Nos.43 and 44.
