From the video description:
Welcome to Episode 4 of The Lost Pins ~ Gottlieb’s Brooks & Dunn Pinball
Brooks & Dunn was supposed to be released in 1996 (the same year Barb Wire was released), but it was made when Gottlieb shut down and ceased operations.
No machines were put into production, though the only part of this machine in existence is a stripped playfield.
There are a few screened playfields, but they were never assembled when Gottlieb closed.
Brian Madden and Gabe Knuth have acquired some of the spare parts that were produced, and have built a playable version of the game..too bad I couldn’t find any footage of it!
Fun With Bonus is the home of the semi-coherent, misguided ramblings of professional and amateur pinball players.
