Got a response to my email to Alan Woods on this RSR....
"Hi
Nice find!
We did sell a lot to one shop in Preston, cant remember the name, the guy used to be a manager at Halfords.
Yes the bike looks 100% original. They are the best we used on some of them they werent genuine Robinson but we use them when the Robinson ones ran out.
Stickers I only have one set that I need for mine, but as yours are intact you could have repros made, guys on radbmx will be able to advice.
Regards
Alan"
So, looks like the bars are original from purchase so the bike is a 100% original survivor
All I need is to get the decals reproduced although I might need some help with this bit
