practical use could be made of any of these items. Only one example springs to mind - mid 50s and a 'Moggie threeler' parked in the Market Square in Ripon, notable for the steering wheel having been replaced by a Neptune control wheel, complete with switchgear, including firing switch! Overwhelming envy and, in later years and 'driving encounters', some anti-social thoughts as to how such a setup could be used
