I'm glad someone pointed me to this thread-
I'm in the process of gathering information and putting together a plan to build our local milk plant. Our Plant was a Rieck plant, based out of Pittsburgh. A 1923 newspaper article said they ship one railcar of sweetened condensed milk to Pittsburgh daily, and 80-120 cans of cream. I believe it was a 6000 gallon car that sat on the siding & was filled & shipped. The railroad also brought in cane sugar in 100lb sacks and coal to fire the two boilers.
I interviewed a local man, who frequented the milk plant 65-70 years ago when his grandfather helped to manage it. It was great talking to the guy and him pointing out what happened in each building and the process. I am in a state of shock at the amount of automation that was present at our plant in the 1940s.
Hoping to have Andre cut the building out once I get finished with the research.
