There is a man in Virginia, Dr. Wyatt Magnem, I think this is how you spell it. He is a math professor at Mary Washington University in Fredricksburg VA (sp). Dr. Wyatt travels to these places often he might be able to direct you to a supplier.I am trying to find his email address if I come across it I will email it to you through this site. Have a great trip.
