Okay, I found it eventually....
It is a one-off sports racer project known as the Triumph TR2-based "Gibbens Special".
The car features a supercharger (of unknown make) and the engine/chassis appears to be in good condition.
Bodywork is pretty crude but for an advertised price of $2,500 in 2010 one can't complain.
I would have thought that fitting a replacement TR2 bodyshell would be a feasible proposition......

A view of the engine/chassis plus a rear view -
