Ah, the confusion here is WHICH year RRA we are talking about! The auction said "1940s" so I assumed it was meant the post-war one since the RRA pre-war ended in 1940 (appeared in the catalogue that year but I can't imagine they were turning them out in the Battle of Britain!).
The pre-war catalogues are very annoying as Raleigh, for some odd Raleigh reason, showed the non-drive side of the machine.
The pre-war RRAs did have a chainset similar to this but I thought the cranks were finer.
Anyway, I didn't want to start another contentious debate around here! This is, afterall, Raleigh and who knows what they did at any given moment.
