[Closed] roadie content: rare frame builder???? what's it worth?

Hi guys,

i wonder if anyone could help me out valuing a bike for me,
i have been given a "Sid Standard superbe" road bike, with the idea of selling it to raising money for a bristol charity,
i know very little about road bikes and wonder if it's a desirable/rare bike?
if so where would be best to sell something like this, the normal forum classifieds,
or something more niche?

any help would be brilliant as i dont really have a clue on this one, and any money raised would be really beneficial,

anyway here are some pics
cheers
