Found it!
This is a 1959 Austin-Healey 100-6, modified by Arnold Zucchi, presumably in the USA. Modifications included a cut-down windshield (lowered 3 inches), seats from a Porsche Speedster, Borrani wire wheels, three Weber DCOE 45 carburetors fed via velocity stacks and a modified bodywork. The car entered the Pebble Beach Concours d’Elegance in 1970 and was bought in 1975 by Garth Hammers. The picture you used was taken on the very day the car was sold by Garth Hammers to a new owner. Then Garth Hammers’ son bought the car again in 2012.
