Not too fussy what I want to be honest, I don't know that much about them and the differences over the years.
I have a '95 nickel P7 which I have owned since new and restored that a couple of years ago. I fancy a new project for this year and a orange/white Clockwork would be my favourite model. I just want something with original components which I can strip and refurb/clean up, have the frame professionally resprayed and then build back up myself. I won't be riding it, once done it will be hung on my wall (same as my P7).
