Raleigh 50, any info?

[wassertreter]

I got a bargain (resprayed) steel frame to roll around town, the seller claims it's a "Raleigh 50 Road Race" and came with 650x28A hoops. Will probably fit with budget 650b wheels, but if anyone has info on the frame, I'd be happy to learn about it, and maybe even attempt a more genuine(-ish) restoration. The Internets don't turn up a whole lot about that model.

Thanks in advance.
