BRITISH KEYS.
180 181.......... A military Key WT8 Amp No2 and a WT8 Amp No2 Mk11. Circa 1940s. The key on the right has the three bridge design with a PO style spring tensioner on the middle bridge. The key on the left has no bridges plus a simplified compression spring tensioner.
183...... Another model here (there are over 100 variants of these neat keys) a KEY WT8 Amp No3. A mine of very useful information on these keys was published in Morsum Magnificat Magazine Number 28. This one has three bridge design and a PO type spring tensioner.
184. ..... Not often seen this one: British RAF KEY WT8 Amp with its Air Ministry markings! Three bridge design again but with the simplified compression spring tensioner.
185 186...... Yet more variants here: A British KEY SIGNALLING No2, and a KEY WT8 Amp with NATO markings.
187+. ..... Two American Military Keys made for the British Army and others: WT8 Amp made by J H Bunnell, New York, USA.
189. ..... British Military Key WT8 Amp No2 Mk111-1.
190. ..... The "S-R COTEL KEY". A British key in two tone grey, made by the late Jack Sykes G3SRK, of Lingards Electronics. (See MM53 page 9).
191. .... British Military Key Type KMK 2.
196. ..... WW1 Army Key made by EDISWAN dated 1918, serial number 6724. I believe these were known as a "Transmitter Vibrating" this one is missing its buzzer that would have been housed under a circular brass cover.
