I found this earlier and downloaded a copy.
I'm lucky enough to already have a hard-copy of the Daimler version of this but having an electronic copy as well has to be a bonus.

Hi Mac,
Thanks for sharing the manual,I shall enjoy reading it.
I don't have a 420 but you never know which cars are going to come along in the future.
Thanks again.
Take care and stay safe.
Andy
