Not a club as such (although you can suppot it by becoming a 'friend'), the Rootes Archive Centre Trust is a registered charity dedicated to the preservation and study of material of historical significance connected with the Rootes Group and associated or successor companies.

This is a truly fantastic collection of material: the complete library of engineering drawings from the early 1960s to the end of the Chrysler era, and including anything from the late 50s that was modified in the 60s; so there's a lot for Minx/ Rapier/ Gazelle and Humber ranges, plus everything relating to Arrow, Avenger, Imp etc.
