Thank you all for your very helpful and quick responses. I did in fact buy it. I am just debating whether I should keep it, or sell it and continue my search. I have to say, I was slightly dissapointed with how it looked in person. Maybe a saddle and grip replacement, and some new creme tyres will fix that. But it is going to be an investment of time and money, so wanted to be sure it is worth it.

Good to know that it is at least one of the Raleigh bikes and not some lower quality Asian copy. I will go out there with a torch tonight and see if I can use some of this information to identify it. One thing I am not sure about is whether the hub is actually Sturmey Archer. It does'nt actually seem to have the usual Surmey Archer print on it. It only says Dyno 3 Speed (if I remember correctly). Is that normal for the Sturmeys or have I got something else?

If any Raleigh expert has any idea what I am looking at here, your input is welcome.

PS: Thanks for the heads up about the breaks. Maybe I'll have to replace the front wheel with an alloy one. Last thing I want is for her to end up under a bus cause I bought her a dodgy bike.
