Sorry, can't be those dates. I cannot comment on the start date of 1954, although I would have expected it to be a bit earlier if anything. The W202 was replacd by the W404, I never saw much difference between the two with the exception of the floor tools, although perhaps there was some increase in the motor power and possibly it changed from the gold finish to a different colour. Vactric went out of business in early 1960
