One other thing that made me hesitate to identify it as a Raleigh Professional is the rather abrupt straight-bend-straight profile of the forks. Most Worksop/Ilkeston bikes of the period have a more elegant, gradual bend, either maintaining a constant radius, or tightening towards the tip. Perhaps this was a Friday afternoon bike.
It would still make a fine project for someone, and it's a very generous offer on gerryattrick

Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
