Awesome Mike - PM received also.
I will see what I can salvage this weekend and get back to you.
The paint I will leave to last, that's if I do anything at all, am inclined to leave as is - such an intriguing patina ...
Having said that: I will tidy and touch up areas of steel after dealing with minor rust where required.
Do you - or anyone - know if there is an accurate aerosol can available.
And/or what paint code/name am I after?
Seats now: I need replacement backs - what other models are interchangeable?
Cushions the same? Where they vinyl or canvas covered - what colour?
Geez, computer is running out of question marks ...
And Geoff O - challenge accepted (once I have a working clutch)

Andrew the annoying 10-year-old.
