In the course of this restoration we’ve come across some useful and interesting* pages. *Your mileage may vary
History and background information
A-series engines, history and comparison on Wikipedia
Awesome photos of early Mini details at the 1959 Mini Register
The best article I’ve found about the development and production of the Mini is at AR Online, but the whole website is fascinating. For me.
Technical and mechanical information
All about the Mini’s wacky clutch setup at Minimania’s Clutch FAQ
A clear and very readable guide to welding and spray painting at mig-welding.co.uk
An in-depth guide to electrolytic rust removal.
