This caving helmet belonged to Dr Edgar Kingsley Tratman (1899 – 1978), President of the University of Bristol Spelaeological Society for many years. ‘Trat’ studied dentistry at Bristol, graduating in 1924. His career included over twenty years in Singapore, where he built up the dental school at the University of Malaysia.
The Cromwell Protector Helmet is made from layers of laminated paper. The lamp uses calcium carbide and water, which react to produce acetelyne and provide a flame. In the 1930s the helmet was advertised at the price of three shillings, with the lamp at three pence extra.
