lizard Lighthouse, “Sounding“ for fog. 1997

This was my boss at the Lizard Lighthouse, Fred Rosewall, Principal Keeper. This is, the short cut version, for “Sounding“ for fog. It relies on a certain amount of air already in the holding tanks. Otherwise, it takes a bit longer to get up to the required pressure. (Gardner LW4 engines, Reavell Compressors)
