Buster 1966.
The Duke's Spook is not the work of anyone trying to imitate Reg Parlett. It is the fine work of AP comic strip veteran Arthur Martin who drew all kinds of strips for AP titles from the 1930's through to the late 1970's. For example Charlie Drake was a strip he drew for nearly 10 years (1958-1967) in Radio Fun and then Buster. Thanks Kashgar for the info.
