Easiest way to get a close ballpark is to check the datestamp on the Sturmey AW hub, if I had to guess I'd say late 60's judging by the chain ring on the crankset and the half chainguard.. (they match up with my 67 superbe) Also, the less bronze in the green more olive (as far as my experience tells me) is the 60's as well. I'm no raleigh expert, but that one is close to the ones I know.
