The components are similar to what was on my Maserati, but the frame isn't the same... I'm going to guess '74 by the components, particularly the Pivo stem and Barilla brakes.

What is the BB shell width? 68mm or 70mm?

It looks like a low-mid frame, but seems to have nice wheels. Should make a nice fixie. Its oddball bikes like this that make good conversions, not the pristine classics that a lot of people seem to want to convert.
