Great story, great game. One of Norm Clark's best designs.
I had a nice RB once, but needed room and ended up selling it. Miss the game.
I had picked it up from a fellow in PA who worked for Herr's snack food company and he gave me a big bag of snack foods (pretzels, chips, cheese puffs, etc) for the ride back home. I bought it as a total project because the PF and cab were in nice shape. When I got it home, found that every score reel and stepper was seized solid with some kind of red goo that resembled the coating on a candy apple. The seller didn't do it; he was just flipping the machine. I had to completely disassemble every moving part, soak it, and scrub with an old tooth brush. Then, I rebuilt every bumper with new plastic parts: 5 pops and 2 passives; what a piece of work. The Riverboat ended up playing great. I should have sold something else
