I recently acquired a Raleigh Sirocco for free and I've searched Sheldon Brown's website, Google, and any old online Raleigh catalogs I can find, and I can't find any information on it.

It seems to be a racing bike or sort, due to the lack of fender/rack eyelets. It's made of Reynolds 501, has Weinmann sidepull brakes and levers, concave 700c rims (don't remember the make), Sugino GT cranks, Sakae handlebars, Suntour derailleurs and braze-on downtube shifters, and a Brooks Vitesse 500 saddle. What is this thing worth, and is it any good? I'm hoping to bring it back to its former glory.
