too bad it's so rusty...it's old and vintage but not so very "special" as to warrant the huge investment it would take to restore it, IMHO. If you are going to give it away, it probably could make a nice SS for somebody. I reckon the shift levers, if in good shape, are the most valuable things on it, the Simplex derailleurs look to be toast, but if they are alloy and not plastic they might be worth some $ to a collector. I'd try bathing it in oxalic acid and keep it "patina'd".
