Keo surfboards
There were such a lot of surfboard makers in the UK in the 60s and 70s that theres still quite a few I haven't mentioned. One is Keo, who made custom and more affordable popout surfboards and kneeboards ,and bellyboards. I can't find anything out about Keo so can't be sure where they were made - Cornwall or Devon is a pretty safe bet. This one is from Alex's collection, an early / mid 70s single fin.
