ooh - thats old. Cranks will be fun.
If the paint was in good condition with a healthy patina, have you considered a modernish restoration? those brakes are just awfull to use, god only knows how anybody managed back then (they were used in races FFS!)
Nowt wrong wi' them brakes, lad. They wuz orlrite when I wuz a lad! Why do yer want ter stop in a race? Idea is ter go fast!!
New blocks (and possibly cables) will probably improve matters a lot. I've got a pair of the sidepull Weinmann 500's on one bike and they work OK - but I have got modern 'all-in-one' type blocks fitted.
The frame looks fine. If it was mine I'd go for a 'patina' restoration. Clean and polish the frame with a bit of T-Cut, Brillo and Duraglit the alloy fittings etc. It'll come up lovely!
Today is the yesterday of tomorrow.
