I've been doing some research which has led me to a group of experts and ex-employees at this factory.
Shortly they will be having a reunion 'get-together' and have offered to try and answer any outstanding questions about the factory.
Of course I already have a list of my own questions and some statements elsewhere on this board which need to be confirmed as correct.
If anybody has questions to add then I'm happy to include them. (Please try to make them clear and specific!)
Please post any photos to me via my website (Mod: email deleted) and I'll gather everything together.
