Yes the Freewheel may be worth something if it's in good condition spins and catches smoothley and the cogs aren't in rough shape. Pull it of the wheel and clean it up and you should be able to get $25+ or so for it on Ebay not big bucks but way more than it is actually worth. The wheels and freewheel you picked up are a score and completely suited nice match for and vintage correct for the bike.
