A very rare machine, with few found, the only known advertisements for the Flexispeed shaper was published by the well-known Barnsley dealers Garner during 1951. Flexispeed were based only three-quarters of a mile from the factory producing the very popular hand-operated Adept shapers, but, instead of buying those and putting their own name on them, they bought instead from Portass. The "Flexispeed", in having a 5-inch stroke, fell between the Adept 1A with  4" and the Adept 2A with a more useful 6.25". Other competing machines of a similar type made during the 1940s and 1950s included Perfecto, Graves (a re-badged Adept), Tom Senior, Omerod, Robblak, and E.W.Cowell
Several shapers sold as the Flexispeed and Portass must still exist and should you have one (they are easily identified by a tool slide of distinctive shape) the writer would be interested to hear from you. Photographs of a surviving example are shown below.
