Ah, now that rings a bell. My best friend had a deep maroon/burgundy Raleigh, I cannot remember its name, but it was a bit more "tourey" orientated. It had centre pull brakes and was very "classy" looking but I definitely remember it having a hand-assembled nameplate which I'm pretty sure was Dave Brown.
I don't think it was assembled by Dave Brown. Dave was a frame builder. One of the very best. He worked at SBDU in Ilkeston under Gerald O'Donovan. When that site closed, he moved to Nottingham as SBDU was absorbed into Raleigh Lightweight Division.
I can't remember all the assemblers, but there was Clive Hodgson, John Spray, Kenny ?, Carol, (who also did the bar assemblies), Brenda Heard, (who also made wheels) Neil and Alan ? two brothers who also did the wheels. There were others, but I don't have the names handy.
