That close up of Slim was taken with the Westminster prototype ,which used Sikorsky S-60 dynamics married to twin turbine engines.could have been a good machine if Westland had stuck with it. Instead the technology went back to the US,leading to the S-64.
Is Slim still around? I know most of those listed in the Flight article are no longer with us ,although have recently been in touch with John Morton and Sox Hosegood ,and I think John Fay is still alive.
