Wanted: cheap old frame (reynolds or columbus)

im after an old frame (531 or similar), structurally sound for stripping down and restoring as a project with my dad for some bonding (aww), so paintwork can be scratched to bits, just as long as no serious damage to the tubes.
preferably something like a tatty holdsworth (easier to get the decals?)
not fussy on the size, any will do
cheap as possible
thanks!

what size?

forgot to mention, not worried really, any will do. cheers for pointing that out

Bump

Got a Raleigh Zenith Reynolds 501. Structurally sound, some surface rust and scratches etc. Would want £30 for it. Frame forks and headset.

I have a falcon frame and a dawes galaxy both reynolds tubing: http://www.lfgss.com/thread103905.html
