Hi, this is a bit late in the day, but I only just stumbled across this site and the threads about the old Cincinnati factory in Erdington..
My Dad spent over half his working life in this factory and I have vague memories of visiting the place for a christmas party in the very early 80's. The parts of the building that stick out in my mind were the entrance foyer with the old antique machine and the computer room (I think on some lower floor).. At that time it was full of some kind of mainframe with lots of tape machines. Fascinating place for a 10 yr old kid to see around 1980.
So yeah, my Dad died fairly recently so seeing these images means a lot. Especially as the building is also no more. Seriously - belated thanks for posting these photo's (I hope the guys who put these threads up are still active here).
