The rims appear to be AVA which were OE on Raleigh Pros in the early 70’s. They also came with Campy brake cables and silver/gray housings.
Measuring Raleigh frame sizes appeared to be BB center to intersection of where the top of the top tube would be, which with the Professional is above the scalloped top of the seat tube.
The shop I was at sold a bunch and parted out a lot more when Raleigh would have a sale on them for not much more than the price of the Campy gruppo.
