I'm sorry but this is wrong. 103 is not the SCAR Stradale and NOT in the Louwman museum but with a private individual...Last data I have (3 years ago)
750.33-103. Car delivered to SCAR, Alfa Romeo dealer for Florence and Tuscany. Used for road and hill-climb competitions (Spartaco Dini & Guido Nicolai). Slightly lightened for racing purposes, with fixed windows and without sound isolation. Later sold in Germany and used by Weber, Fischhaber and other drivers. Sold to the Kaus collection (Rosso-Bianco Museum) and finally to Louwman collection in the Netherlands. Probably restored (Paul Grist?) and fitted with air conditioning and four exhaust pipes, winding windows and two rear mirrors on top of each front fender.
