I have posted a guitar belonging to my friend and former bandmate Kevin Cox on eBay (he does not have an eBay ID). It was originally sold to him by Djangobooks as a "Gypsy Mystery guitar from a well-known California luthier," who happens to be Peter Zwinakis. It was one of his prototypes. It is in excellent condition with only minor playing wear and is listed at an outstanding price. Kevin got his hands on a '91 Dupont last year, and the Zwinakis has been superfluous since, but it is a great sounding instrument.
