Terry, Ken, great stuff...
This is what I could find.
This car, chassis number 0382AM, was first owned by Bill Spear, who drove in many U.S. sports car races in 1953 and 1954, winning at the Thompson Raceway and at Watkins Glen. After he sold it in 1955, the car was raced until the 1960s. It has never been restored. Its also noted to have been sold January of 54. Who really knows?
Ken, if I could add a bit more history, perhaps simply for posterity:
Way back - I'm talking way back, like around the time my father was born - Pinin Farina had two listings for 0376 AM. It went so far that Ferrari's ADS (Assembly Data Sheets) showed two 0376 AMs - at which point, one of them was renumbered. The car that was renumbered was this one, 0382 AM, a RHD Pinin Farina Spyder, chassis type 108-102, motor type 108, gearbox type 108/102 #29 D, rear axle type 102 #45 A, Pinin Farina body number PF 12568 (though that's still unconfirmed because of the mix up with 0376 whose Pinin Farina job number/body number is PF 12569) - but interestingly enough, 0382 AM is the 14th competition Ferrari listed as a 1954 model, not '53. Also, I have zero race history for 0382 in 1953, but plenty of race history for 0382 in 1954:
On Sunday, 07 March 1954, Bill Spear, with co-driver Phil Hill, DNFed at the 12 Hours of Sebring, wearing number 7.

In June, 1955, it came up for sale through Imported Motor Car Company of Centralia, IL. Advertised as ex-Goldschmidt, new records, Giants Despair, finished fourth in Mexico, ready to race, extra wheels, Pirelli tires.
In Volume 4, Number 2, it was listed in Great Britain's Ferrari Owner's Club roster with Joel Finn of Poughkeepsie, NY; identified as ex-Spear and winner of many USA races.
From 1974-'82, it was listed in the USA Ferrari Owner's Club roster with J. B. Gunn of Mt. Kisco, NY.
It wasn't seen again until Pebble Beach, 2010, at which time it was, and still is, owned by Andreas Mohringer of Austria. Mohringer also brought it to Cavallino earlier this year, where it was also presented at the jet reception.
If anyone can add anything to this car's history, that would be greatly appreciated.
