The first is advertised as a Stimson 3-wheeler but I don't think it is that (ad here). The front number plate suggests it could be a 'CTS' but I cannot find any information whatsoever about a vehicle with that name, not in Chris Rees' excellent book 'Three-wheelers', nor in Steve Hole's 'A-Z of Kit Cars, nor on the web... Number two is a one-off, known as a Cannon. It is advertised in Germany on a German website, while the thing itself is located in Spain, on Spanish plates (ad here). Last of the three is a 'Leyland Skip' (what's in a name?), which is perhaps the least obscure of the three as one of my books does mention that as built by J.J. Calver Industrial Engineers in 1991. Two are said to have been made, although the car pictured in the book doesn't look quite the same as this one... (ad here). Now, who dares...
Advertised as a Stimson 3-wheeler but I don't think it's that. A CTS then?
