"Third Symbol is the year of manufacture, e.g. 4-9 would be 1974-1979, 0-3 would be 1980-83, and then the sequence repeats. Thus, 'WH4003203' would be the 3203rd frame built at Worksop in June 1974. In 1982, when Worksop production was moved to Nottingham, the division continued to produce frames with the 'W' designation."
