The top left photo shows a building that looks like just another building in an industrial park. But as Forgotten Delaware, and now you, have found out, it is indeed a historic structure. The rest of the photos show that while this building has a new face on the outside that hides (and preserves) it's past, it's inside tells us it was built in a much earlier time. This building was know as the "New Machine Shop" at the ACF/J&S plant, while we don't know exactly when it was built we know it was before 1927.
