Hi I just happen to run into a friend yesterday who works for the Powerhouse Museum in Sydney and he mentioned that not so long ago one of the curators from the Powerhouse had been asked to catalogue the Arnott's archives. He said it was quite a big job as all they had done was store everything, in no particular order in a big room. It was very weird to come home and find a message posted about Arnott's. Anyway it may be worth contacting the Powerhouse. Regards, Dianne
