Mike, just had a long chat with an old (86) pal of mine who worked at Crossley between 1948 and 1957. He was a bodybuilder and mainly employed on double decker bodies, but also worked on a number of Matadors that came in as running chassis cowls (as opposed to chassis cabs) for the cab and rear bodies to be constructed. He doesn't remember the numbers involved but referred to them as 'a fair old number'
