Major assumptions made here based upon very little evidence. I would pass as your gruppo from 1979 could likely be better used on a more deserving frame. This may be a Masi, but it is most definitely not a MASI. The people in the know will not be impressed and the people not in the know won't even know what a Masi is. Plus if you are looking for an inexpensive great riding bike you can definitely find something much better for less money.
