Early Tommasini's are kind of rare. They do not have engravings like the later bikes to confirm their origin.
I can't tell you if that bike is a Tommasini, although it is definitely a nicely built bike.
The only other early 70's bike I could find online is a road model and does not share any of the same features. The creased seat-stay top is a distinctive feature on the ebay bike.
I do think it's overpriced for a frame that needs a full restoration.
