The Ackvoke was an air gun designed and manufactured by UK-based company Accles & Shevoke Ltd.
The Acvoke pistol was developed after the end of the Second World War (1939 - 1945). The post-war market for air guns proved profitable, and the leading manufacturer in the field was Webley & Scott. Accles & Shevoke Ltd. designed the Acvoke as a rival for the popular Webley Junior pistol. The Acvoke was patented in 1946, although it was largely based on the German Tell II air pistol. A distinctive feature that the Acvoke borrowed from the Tell II was the innovative trigger guard, which was hinged so that it folded when the pistol was broken. When broken, the pellet was lodged in the breech end of the barrel. The Acvoke was rather popular in the late 40's and early 50's because of its cheap price and very small, sleek design.
The Acvoke appeared in the 1968 film if.... in the hands of protagonist Mick Travis.
