Indentify this Delage?

Hi All,

This is a picture of my grandmother in 1950 in her Delage - I've looked online but can't really identify it, is is a Diss a D1 a Torpedo? Anyone want to have a guess or two?

Thanks
Adam

For you vintage buffs, the last pic shows her getting towed by a BMW 328 Roadster (1936? model)
