The damage done by the Las Vegas Butcher continues to haunt this hobby.
Years ago, Bill Whelan (RIP) documented that the Butcher was putting bogus jackpots on the Gem Vendor, which, according to Bill, was never produced with a JP and only came with cigarette reel strips.
This machine is currently listed on Flebay and, of course, the seller refuses to hear that his machine may not be all original.
