Oscars Wild Ride & Wacky Bubble

[Denbo]

I recently purchased several Oscar's Wild Ride and Wacky Bubble kinetic bubblegum machines and am curious if anyone might have manuals for them? The (2) Wacky Bubble machines are the larger versions, were never installed and are in pristine condition. They function flawlessly. I have 3 (first generation) Oscar's Wild Ride machines. One is in excellent condition and two are in disrepair for spare parts. I have them set up in my "Man Cave" for kids to play with and will not be used for vending. Any help or suggestions would be greatly appreciated!
