Thanks for the excellent 1938-show data, David!
I'd love to see a pic of the '42 model you speak of.
Attached here are scans from the 1948 edition of
Motor Specifications and Prices, showing the British Chryslers from 1925 through 1940 (and 1946). Note that Plymouths are shown here as such from 1938 to 1940, but some of the Chrysler models are also Plymouth-based. The Kew appears to be one such model in the later years.
