mchomin,
Have you tried looking on the bottom for the bottle manufacturer's marks?
I'll admit I have not seen but 2 of these over the past few years, and can find no references to the manufacturer.
Aside from this one you have, I have seen another in Italy, but the seller
knows little about his bottle also.
Curious to kow what you find out!
Cheers,
