Put a wanted ad up, loads of very nice members only happy to help out. It will be great whatever you do. Another one saved.Thanks for all the good gen. @Markybeau has clarified the age and has offered a recommendation for a respray.
That said, it's all looking promising and I may just do a really thorough clean up/touch up job as suggested by @Guinessisgoodforyou but first I'll look into the full respray options.
I'll build an 8 speed wheel to keep the authenticity going and I may well have to source a set of good condition Shimano 600 shifters as it looks like repairing the broken lever isn't a realistic option. If I can get a single RH lever that may save a few quid and I can then polish up the LH lever (incl new decal buttons), as it's in reasonable condition.
Thanks again
