This model was constructed in two distinct series: the 'LWB' (long wheelbase), between 1958 and 1960, and the 'SWB' (short wheelbase) from 1960 to 1962. The latter example wasn't actually completed until early 1963, with sub-divisions relative to body and mechanical details. A removable hard-top was available for both series.
This is a special competition model with a testa rossa type engine. This model is among the best 250 GT SWB Spyder: the current owner rejected a $10 million offer for it! Size: 10"
