Well Bob!
I gave it a Good Try!
Sent out numerous photos like the ones below to everyone I could think of and no one has ever seen one or was familiar with it!
After communicating with Marshall Fey he was only able to tell me he knew of Tom Gardner however he had no information on him so unless someone else out there has any information or has seen one of these Mechanical Progressive Jackpot High Tops it may remain a mystery My Friend!
If Marshall didn't have any information being based in Reno for all these years I don't know where else to search!
I hate to use the word "Rare" as it is overused so I'll say this puppy may be very "Scarce" but as one person replied to me a six legged pig is rare but who wants a six legged pig! LOL
But it definitely is a unique revamp for sure so putting a value on that little puppy would be hard!
Bona Fortuna!
