I found that page yesterday, and tried to contact the guy, but the page hasnt been updated since 2001, and the email was no good.I have sold a few of these, so I would be interesteed in selling some if anyone is interested. I also have the original slips that were kept behind the coin box and stamped when they were serviced. I saw a guy that found one restored, purchased it, and was happy that he only paid $600.
