Description

A Type F Morse key used by the R.A.F. and Canadian Air Force during World War II in aircraft such as the Lancaster, Halifax and Wellington. The case, made from compression moulded phenol formaldehyde, encloses the operating parts, giving it protection in an explosive environment. It is hinged at one end and held closed with a metal clip which can also be slipped over the skirt of the knob to hold it down thus sending out a continuous signal to rescue craft. This model was also known as the Bathtub Morse key due to its resemblance to an old fashioned bath tub.
