WW2 10F/7741 Type F Bathtub Military Morse Key

This is an iconic WW2 10F/7741 Type F Bathtub Military Morse Key. It is in pretty good used condition with a few scuffs and blemishes commensurate with age and use.

Material: Bakelite case mounted on a Tufnol rectangular base board: (Tufnol comprises layers of toughened paper/cotton temperature resistant up to 200-240˙C).

NB: An image has been included of the base of a typical unmounted bathtub key for comparison.

Approximate Key Dimensions (WHD): 13.5 x 7 x 4 cm

As used in RAF Lancaster, Halifax and Wellington Bombers, in conjunction with the T1154 Radio, during WWII: see photo. It is commonly known as the bathtub as it is shaped like an old fashioned British 'bathtub!'

A clip holds the bathtub key cover closed and can also be extended to depress the edge of the knob so that a signal can be sent continuously in the event of an emergency. The fact that the key is totally enclosed meant it could also be used in a flameproof environment.

A great find for all collectors of military keys or radio communication aficionados!
