Scott, I would say you are correct assuming the pipes were below ground. Vinegar has a high proportion of water that will freeze. David

Scott, I enjoy giving the clinics at the RPM's. I even have a few ready to go, whenever that is. As far as a photo showing the piping, I do not have one in the book. But the diagram on page 94 sums up

Sorry, I forgot to sign my name David Leider

Scott, You are correct. I have photos of 3 Speas Vinegar cars in my book. There is also a 2 page history of the Speas company. I still have copies of my "Pickle and Vinegar Makers of the Midwest" book

Tony, Thank you for the nice review David

Fritz, Thank you for the excellent review of my book. I am glad you enjoyed reading it. I enjoyed writing it and discovered a lot of things I did not know about Early Chicago railroading and the B&OCT
