Air Ministry 10F/7741 Type F Bathtub Military Morse Key In Its Original Box

This is an iconic WW2 vintage 10F/7741 Type F Bathtub Military Morse Key In Its Original Box. 

Although NOS, there are a few small storage chips on top of the morse key (see image with chips magnified), and the membrane inside the key needs replacing. Otherwise, it is in pretty good unused condition. The price has been adjusted as a consequence of the defects.

The outer pale grey cardboard box is intact, with discolouration and blemishes. There is one label on the packaging as follows:-

This Box contains One Key Morse Type F, Ref. No. 10F/7741, with AM and a crown.

Material: Bakelite case and two-part cardboard box
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!
