you should post this (or post a link to it) on the classic and vintage subforum. There's someone over there named bianchigirl who will be able to give you more detailed information on that bike. But it is definitely worth more than $50 by several times. With an overhaul, probably at least $200. It's a nice mid level frame, Ofmega crank and ?Athena? Campy derailleurs. And bend those nice celeste water bottle cages back into shape!
