I'm pretty sure this bike is a UK or Euro-only model. I've never seen anything like it and can't find anything about it online -not even a picture of a similar bike. Searching Google Photos turns up a few hits on "Raleigh Courier" but they are all diamond-framed versions.
This is definitely a rare bike stateside. I bet my friend will be the only one riding one like it at the Chicago Tweed rides.
