Many happy returns of the day, Simon! All the very best!
To anyone considering the tour I'd say, "Go!" I was on the last one and it was a brilliant experience. Everyone at Ilford was extremely friendly and helpful and the scale of the operation and the attention to detail was a real eye-opener. (The pies were superb too!)
I'm going to hang back on this one to let people who haven't been before have the benefit of the "Ilford Experience", but I do heartily recommend it to anyone who can attend. Some shots from the last one can be found (there was a url link here which no longer exists).
