When my husband was stationed in Italy, we used a catalog called Peter Justesen to buy whatever we wanted in whatever voltage. I wanted a Singer and all we could find where we lived was Bernina, so we ordered through PJ. Not everybody can use them though. Here is what it says in their web site "Our core business is the supply of goods to the diplomatic community worldwide. I.e. diplomats in various embassies and consulates around the world, the UN and any other International Diplomatic Organization. We also supply to private companies and organizations and individuals who enjoy tax and duty free privileges."
If your friend belongs to any of the above I would keep Peter Justesen in mind. Good luck!
