Not of the Case plant itself, but I have gone through the Case-Zippo museum. It is actually attached to the Zippo plant and you can see part of the assembly process from a window in one of the rooms.
My father-in-law and mother-in-law both retired from Alcas. I think almost half the family on that side work there actually haha. I have a few friends that worked at Case and the wife actually worked in the office for a bit before she got sick.
