Looking for Information on Mistral #109.A1.966

Good afternoon,

I am assisting the German owner of a Maserati Mistral 4000/GT trace the North American ownership history of his car. Originally it was gray in color and sold by Foreign Motors in San Francisco. Factory equipment included AC and an automatic transmission. Somewhere in its life, it was fitted with a popup sunroof. It was last owned in North America. by Gerhard "Gerry" Blauth of Sacramento, CA and Vancouver, BC. In 2014 it was sold to a doctor in the Netherlands, before being recently acquired by a German collector who is undertaking a restoration.

Any and all information will be gratefully appreciated.

Thanks and take care,

M. M. "Mike" Matune, Jr.
