ACVOKE (ACCLES and SHELVOKE) .177 (4.5mm) AIR PISTOL.
Acvoke (Accles and Shelvoke Ltd. Birmingham) .177 calibre air pistol. SERIOUSLY RARE and SERIOUSLY COLLECTABLE. Apparently these were produced from 1946 onward for a period of 10 years. Given a limited period of manufacture AND that is now around 65 to 75 years ago you can easily guess why these pistols are rarely available for sale.
