I owned a Hadcock GH228 Superarm, purchased while living in London in the mid-70s. Recently swapped it to a gentleman who wanted it for his vintage London Decca cartridges.
It was a low mass, uni-pivot arm, best suited to mm cartridges. The Shure V15 was a favorite back then as I recall. It was a pretty solid arm at the time, better than the Mayware Formula 4, also a British uni-pivot design which I still own.
HiFi+ magazine did a review of a GH242 SE in their issue 13, which unfortunately can't be read on their on-line site:

Perhaps you can contact them for a copy.
