The Stabilimenti Farina body number for chassis 102 is "8836". Chassis 103 (one of two valid Cisitalia cars with that chassis number) has body #8837. Each of these (chassis 102 and 103) seem to be solid "1948" examples rather than "1947".
Ursula Messmer of Kloten, Switzerland was the owner from whom Rob de la Rive Box purchased the car around 1966. It had a Zurich license plate that might be researched if one has the right connections? That information came to me from Rob Box himself.
Although anything is possible, it seems to me that a USA racing use history is no more likely than a European history, whether or not any racing was done by this particular car.
If you wonder about the statement that chassis 103 is one of two cars bearing the chassis number "103", then you may wish to know that one car bearing chassis "103" is very similar to the subject car, also with a berlinetta body by Stabilimenti Farina bearing a body number consecutively later than the subject car. The engine number is also one number higher. We should probably avoid assuming that they were completed in numerical order? The other car numbered "103" is a cabriolet by Vignale and its history seems to begin 1949 rather than 1948. Its Cisitalia engine number is much higher.
It has proven to be quite common to find duplicate chassis numbers on Cisitalia cars that can be documented as being historically valid. It is not common to find duplicate engine numbers from Cisitalia. My studies reveal more than 20 examples of chassis number duplications thus far. Sometimes there is a letter suffix that differentiates them and sometimes there is not. Each story is its own. But, this also tells us that we cannot simply take the highest chassis number and lowest and do simple math to arrive at any meaningful production numbers. More cars were built than a simple count implies. This also allows us to think it is POSSIBLE that there may be another car numbered "102" that is simply not yet known to us?
Nino Borsari's car (mentioned above) was chassis 036 and it has Pinin Farina body number "9935". It had a declared chassis origin date in its papers that stated "20 October 1947" but was first sold and registered (in Trieste) one full year later. Borsari, an Italian champion bicyclist, purchased the car during April 1950 and registered it in Milano before taking it with him when he moved to Australia later that year.
Entertaining stuff, the study of Cisitalia production and histories!
