I put the ?? because I wasn't sure of the year, but I'm sure it's a raleigh Professional. Raleigh made a bike like this in the late 1960's. Before they went to the fastback seat cluster, for a while they made a bike that was quite non-Italianesque - Vagner box crown (not sloping), although Rich Pinder's example 1969 bike has medium-point lugs and the later sloping crown.

The semicircular centerpull arch is a trademark raleigh/carlton item. The wrapover stays on a Raleigh date the frame as being pre-1973.
I suspect that the bottom bracket braze-ons were more a function of when campy started to give away the downtube clamp-on cable guides with a grouppo order. Can anyone provide a date for this ??
I have a 1967 raleigh competition (~ International), chromed nervex lugs, campy dropouts, and BB braze-ons. For a year or two Raleigh offered a "V" shaped centerpull braze-on that accepted standard 5mm(?) weinmann barrel adjusters - not 4mm as on the later and earlier bikes.
I also have a 1977 competition with "soft triangle" lug cutouts and campy dropouts. From 1968-1976, I think that campy horizontal dropouts only appeared on the international (w/nervex lugs) and professional models.
