I don't know as if you will find contact information for Bernardi, they don't sell directly to consumers afaik. I honestly don't know if they are even still producing. I wouldn't be surprised if much like other cast operations, Kinetic bought the molds and name rights and are producing them in India.
Even with said information, I don't know as if you would easily overcome the language barrier. I have had a very mixed reception from European moped suppliers/fabricators.
