Quoted from Mitoska:
This Brooks & DUnn one comes to the Ohio Pinball show every year, it may be the only one.. not sure
Quoted from ForceFlow:
That's the one that was built from parts a few years ago, rather than an original prototype. Either way, it's still an interesting looking game.
I’m pretty sure there is a thread somewhere documenting the Brooks & Dunn games, I believe they had enough parts for a few machines and they finished the coding and such for it as well.
So more than just a couple out there. Should be less than a dozen or so
