After getting thoroughly confused I happened to look on my coffee table and there on top of the stack of magazines was CAVALLINO #150 and on page 20 I found an ad for a 1969 Ferrari 212E Montagna spyder offered by RM at the Biltmore in Scottsdale, Jan. 20th, 2006. I look up this listing and there's RM saying they sold it for $1.650,000 on that day and that it was chassis number 0862--the auction catalog tells almost the whole story including its stint as a show car bodied as the P5. Here's the auction catalog listing: 1967 Ferrari 212 E Montagna | Vintage Motor Cars in Arizona 2006 | RM Sotheby's The part they left out is any mention of a Japanese collector. They say "At the completion of the 1971 season the 212 E Montagna was sold by Ferrari to noted collector Pierre Bardinon. It was acquired from him by noted enthusiast Jacques Setton in the early 80s. The original 1969 body had in the meantime been fitted to Dino s/n 022 which fortuitously also found its way into Settons collection and while there the 1969 body was reunited with its European Mountain Championship chassis, 0862, and Tipo 232 engine, 1, to return it to its original configuration." Now that we know it was always a Dino chassis, the only remaining question for me is: what did Bardinon buy it for, and which body did it have on it when he bought it? Seems like there are two race car bodies the car could wear to be "correct" to its configuration in a select time period but certainly the less curvy body (unfortunately aesthetically less pleasing)--the one it was wearing in Scottsdale at the auction-- is the one it wore during the triumphant 1969 European Alpine Championship season.
