All
A pal has posted an unknown frame on another forum, and sadly none of us have been able to identify it.
Two threads

It is a mid to late seventies (seatstay clamp is fitted around the "new" Campagnolo bolt). Takes a 27.2 seatpost, English threaded BB, has all Campagnolo equipment including dropouts. Italian-esque long point lugs, flat fork crown (Cinelli?) Semi-wrapover seat stay attachment--looks almost like a Holdsworth...
The distinguishing mark to my eye is the chain stay bridge. It is fairly small diameter and attached with diamond-shaped bosses that are cutout (so not like solid the deRosa diamonds he used on the chain stay bridge). For someone who knows (?)English frames this feature should be distinctive--you can see the bridge best in the pics in the first thread.
Thanks,
