Are there books out there that cover the farm equipment side of Allis? Something in depth & not just a picture book. Not really looking for a book of tractors AND equipment. Got a couple of those already. Also am curious about anything that covers the turbine & power generation equipment as I only know a little about it. I do recall getting a peek inside the turbine hall, in West Allis, as a youngster. Surprised they didn't turn the pit into a public swimming pool after they closed down. It was HUGE!
