The TOPS class numbers were introduced around 1973 but were later simplified with all the remaining vehicles becoming just Class 119.
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 and John Horne.
GRC&W seems to be the only builder that also added a builders plate (formed of brass).
