For a while, there were two cars known under the s/n 1655.
The early history of 1655 has been undisputed. Finished by Maserati in autumn 1955, the car was directly purchased by Californian housing developer and road racing magnate Tony Parravano. Its first race appearance, however, was in support of the factory cars in the 1955 Targa Florio. For that round of the World Sports Car Championship the car was privately entered by Parravano, but fitted with a 2.0 liter 4-cyl. engine and driven by Fernando Mancini and Benoit Musy. Unfortunately the car retired. Re-engined with a 1.5 liter 4-cyl. motor, 1655 finally arrived in California. At Palm Springs in December 1955, Ken Miles drove the car for Parravano and won two races with it. In January and February 1956, the car is raced for Parravano at Torrey Pines and Palm Springs again. After that, 1655 disappears ...
There is no need to tell the Tony Parravano story here again. When the conflict with the IRS escalated in 1960, several Parravano cars were impounded. Other had been brought over the border to Mexico. After some time, however, all the cars were up for sale, both offered by the IRS and from Mexico. The Mexican cars returned to the US. Not much details known. After some more time, ex-Parravano cars were still rather special, but nothing unusual in the international market ...
So when a genuine 150S with a Californian background but apparently only little other documentation appeared around 1990, it was quite reasonable to think that this may have come from Parravano. Over the years this car became known as s/n 1655. About 20 years ago, however, this identification was first questioned and later further research revealed the car as 150S s/n 1674!
A main reason to doubt the above identification has always been the claim by another car to be s/n 1655. Who can detail the story and race record of the real s/n 1655? What happened to it after 1960? In Mexico? Impounded?
