Wow!!!!
I have two Tommasinis of a more recent vintage. A 1994 Sintesi and a 1988 or so Super Prestige frameset.
I am hardly an expert, just a fan. Like the way they handle for sure, and I certainly admire the attention to detail on their frames.
Both of my bikes were id'ed by sending an email to :
info@tommasini.it
Include a link to your flickr set. I have a hunch they'll be quite helpful. Here is a link to their website.

There was a frame that was similar for sale last fall on ebay.de. We tried to acquire it, but the auction came down early.
Are you selling this example or restoring her?
Please let us know what you find out. Love yours!!!!
