Any way you look at it you got a great deal! Nice frame (provided the tubes aren't bent), a selection of parts that are worth maybe five times what you paid for the whole bike and it's got an enigmatic rarity too! Check the frame tubes behind the head lugs with a steel straight edge (ruler?) to make sure they aren't bent or bulged - otherwise the frame's toast. If not, a new fork, chain and rear sprockets and you've got a bike to die for, all for an initial outlay of 60 Euros - I've paid more than that for the same models of rear mech and brake calipers.
