Hi All. Now the sun is out, despite near zero temps, a long Saturday on the Raleigh has revealed it's number 13807QR. At least I think it's a Q, there's a mark crossing the O which I think is part of the Q stamp. It is on the steerer tube, which is the only place left to look. Thanks to all the post replies, I can now post pics. So, replacing the crap seat, tape and respoking the rear wheel and replacing one busted spoke on the front is all that's left to do. Then I can return it to my son who will treat it like s**t again and we'll be back to square one. As I personally don't get on with all that leaning forward business, I don't like drop bars. I'd love to do a flat bar conversion on this because it is a nice light and very nimble frame and wheel set up. Sacrilege among the purists, I know, but more practical around a big city.
