Atco... boat impeller?
Seriously: https://myoldmachine.com/topic/6481-atco-boatimpellor/ (I blame the mad Ransomes Conquest).
I wonder what other weird stuff they made that most of us don't realise?
Many people will know about the Atco car but fewer will have seen the image below of one of the prototypes.
Also of interest may be this prototype edger...
Incidentally, I am trying to source good quality modern images of Atco mowers made from the 1920s to the 1960s to help the current company with its planning for the 100th anniversary next year. If anyone has any images they can send me that would be great.
I'd actually forgotten the car - love the armchair, and the edger is a bodger's delight! The Atcoscythe, whilst a mower, was pretty wacky too.
