I have come across pictures of this golden shortened Mini several times now and remember having read somewhere it was a professionally coachbuilt car. However, I cannot find back anything on it now. It does seem to have been marketed well in its day, though, with a number of staged publicity photographs available, made in 1971 or 1972 or so my limited information tells me. A clue to its origins may be the Swiss made 10" Edgar Schwyn wheels?
The only unstaged picture that I have of it seems to be of a slightly later date, now with Cosmic wheels, added bull bars and a number plate that does indeed seem to be from Switzerland.
I'm sure somebody here will be able to tell me more.
Shortened Mini seems to have been built professionally but information is hard to find

Was it ever marketed as a coachbuilt Mini? Wheels may point towards Switzerland?

I think the number plate reads 'Super Mini '71' here. Who was behind this conversion?

From the files - squeezed in a tiny spot and with added bumpers and different wheels. Swiss plate?
