I have been looking at the history of Fairthorpe. It turns out that there is a cobweb of links between Microcar companies behind all this.
Fairthorpe Ltd was created to build vehicles in June 1952 by Don Bennett, but had to start life as a jobbing engineer assembly company. It had a co company doing Areo engineering called Dart Aircraft Litd sharing the site. In early 1952 Don Bennett had bought the Russon car production company. Connection 1
In October of 1955 Fairthorpe gained a new factory Manager. He was John Green, who had been a manager for Blur Star Garages. The same outfit of this thread, who marketed the Powerdrive from November 1955. The 350cc version of the Atom had failed to sell one unit. So a version was made with a British Anzani engine in it. This car was spoken of as the best Atom by the workers and was used as a firm runabout. However I do not know if the Atom 322 was marketed, certainly there is no evidence of sales. You cannot help wondering if this Connection 2 was more than an idle link. I think not. Maybe the history of Powerdrive mentions John Green in passing.
Clearly connection 3 is the link between the Powerdrive and the Allard Clipper. Connection 4 is the Coronet. I am sure there are plenty more.
From the Fairthorpe point of view there are now three Atomata known. One is a 650 BSA A10 Gold Flash original, Another is a Atomata Major with a Standard 8 engine, (it was at the nec last year) so not a microcar, the last is probably an Atomata 650 that has been converted to Subaru underpinnings in America. So a half point there. No Atom survivor is known of as far as I can make out. Tony Marshall often stated he wanted to find one, but failed. The thing seems to have been a bit of a disaster, as Don refused to listen to his then Manager and engineer, Ken Lowe, who left allegedly frustrated. He it was that invented and made a good living by marketing the Kenlowe Fan. So if an Atom has survived it will be a rare thing indeed.
To see Atoms watch the first few minutes of the 1955 Rank film
'Checkpoint' where some take the roll of being Valta cars in production behind a shot out. Cheesy film but great sports cars throughout, and James Robertson Justice shouting.
