WILDCAT 500 .22RF INFO???

I've checked the Wildcat website and gotten lots of info from it regarding these little oddball .22rf single-shots. However, that website has been out of service since 2003, just sitting there. Does anyone know of any OTHER source of info on these guns? According to what I read there, and what I've seen offered at online auctions, there were several companies made them. Some of those named are Ozark Mountain Arms; Rau Arms Corp., and Precision Arms Division. Any help would be greatly appreciated.

Here's pic of a Preciaion I just latched on to.
