And it does have the serial number starting with a W, which I hear is commonly found on Raleighs?
I concur with those who suggest it's a Raleigh. I'm not sure which one though. It certainly looks incredibly similar to other examples. I don't mind either way - just curious
Dropouts minus any adjuster screw provision plus 2 x sets bottle bosses....if it's a Raleigh, probably one of the cheapest bottom end 531s or maybe a Criterium 501? The Record Sprint/Elan/Kellogg's 501 "family" could only accommodate a single water bottle, although many of the other details tally.
