Under initial TOPS classification in 1973, the DTCs became 143s, but were later reclassified as 100s.
Early vehicle type codes identified the DMBS as a Type A3 and the DTC as a Type B2.
The GRC&W internal order number for the DMBSs was 3879 and the DTCs was 3880 (both batches the same).
Worksplates were carried on the vehicle solebars to identify the builder and lot number. Many of the worksplate images on the website are by Simeon Gaskell.
GRC&W seems to be the only builder that also added a builders plate (formed of brass). The class were noted as having curved worksplates due to the curved solebar. Some vehicles also seemed to carry this unique narrower style of workplate - possibly as a replacement to the original.
