I have just received a message from Dr. Geoffrey Miller, who is an expert on Australian Army Medical Services history. He wrote: “ ... basically the disinfector was a pressure cooker, designed to sterilise clothing in quantity. The pressure was about 5 pound, its capacity was 100 blankets or fifty kits of clothing and sterilisation was carried out for about an hour. They could be used as a stationary machine, such as outside baths, but a steam source would have been necessary and mobility was available with a steam tractor.”
And there is a new nice picture from Australian War Memorial archive Geoffrey added.
Thanks a lot, Geoffrey,
Steam up,
Jan.
