It is difficult to find information about the Certus air pistols manufactured by Cogswell and Harrison in the early 1930's. Very few of these pistols were made and Robert Beeman has described them as the 'Holy Grail' of British air pistols.
The photographs (soon to be added) show an example of the very rare 'target model' with extended barrel and two holes drilled and tapped in the rear of the grip (presumably to take some kind of stock). It is believed that only three of these pistols were ever made.
I would be grateful to anyone who can provide further information about this pistol and some idea of the value.
