Indeed this car is in Switzerland. More detail has been made available by the current owner here.
I had the pleasure of meeting the current owner's brother and nephew at the 2010 Monterey Motorsports Reunion, and they brought with them a great book of details on the history of this Yunick-built Camaro. This car, like many Smokey Yunick creations, is super trick. For those more interested, a great article on this Smokey-built '70 Camaro can be seen in Street Rod Quarterly (Fall, 1971). My old fax machine copy of the article wouldn't scan or show well on the forum.
Mike, when this forum was started up, I sent the present owner the same heads-up note I sent you... So perhaps he'll see our discussion and provide more.
