Telegraph key
The key and spy sets were designed by Captain John Brown.
They are very small and light-weight keys measuring just 2" x 1.25" (50mm x 30mm). [See ref: MM22, page 11].
The B2 spy key has its bracket with gap adjuster on the right as you look at the key while operating.
The post WW2 ones have this bracket on the left. A great way to "Spot the Difference".
ZA 34835 is printed on the side of the base.
The B2 was supplied with a variety of different Morse keys. The most common one in the small British telegraph key shown in the image.
It was usually mounted on top of the metal lid of the accessory box (spares container).
Type 3 Mk. II (B2)
The British Type 3 Mk. II, commonly known as the B2, is arguably the most well known spy radio set used during WWII.
It was designed in 1942 by Captain John Brown at SOE Station IX, and manufactured by the
Radio Communication Department of the SOE at Stonebridge Park.
The set was issued to agents and resistance groups and special forces operating on occupied territory.
The official designator is Type 3 Mk.II but the radio is also known as Type B Mk.II, B.II and B2.
The same one was later used with the Type A Mark III (A3). Other keys, such as the ones in the images , were also used and/or supplied with the B2 radio.
Many operators had their own preference for a specific (external key).
