I thought I might add that Kodak ran daily tours for anyone who wished to visit at about 1:00 every day of the week until about 15 years ago. They stopped due to lack of interest.
I can remember 20+ years ago when the lobby of B26 on Ridge Road was lined up with guests and there were 2 busses waiting at the side door, and when it stopped they barely filled a single bus. Much of the tour was through dark areas where emulsion melts were prepared and chemicals were assembled for making and coating.
Kodak also ran a limousine tour with guide for VIP visitors through the plant and then a tour through the research labs. These tours were carefully choreographed so that even blackboards were covered and a security sweep was made to remove all loose film samples. I remember these, as I was guide for more than one Japanese VIP from Fuji and Konishiroku, but I don't remember any from Ilford. I often used my own office and labs as part of the tour, as I could guarantee it was swept carefully at the right time.
Kodak had a sales store around the corner the sign in desk for the tour. They still have it there for people who wish to buy film, cameras, T-Shirts and other odds and ends. There were no goodie bags AFAIK. A few tourists still drop into the sales store AFAIK, but not anywhere near the number in bygone years.
