Hey Chris, always go with what you like- never mind the notional value. Maybe a potential buyer would prefer your choice anyway..
Think you're right about the paint- the white is the base, so if you found orange on the bottle bosses your frame was probably all orange, like mine.
The decals on the white Clockwork look great. I wish mine had black lettering, much better than purple- too 70's for me, even if I was a teenager then (and I was)..
Regards, Steve.
