I'm pretty sure the two-door tourer in the bottom two pics is a 'flatnose' Morris Oxford. Possibly a Cowley (lower-spec version of the same car), but I'm not enough of a pre-war Morris expert to tell the difference, if it's even possible from those pictures.
Brilliant! Thank you for your helpful responses. My wife is chuffed to bits and now researching Triumphs and Oxfords. It’s the most interest in cars she has ever shown
