Morelli was an Italian coachbuilding firm based in Ferrara and active in the 1950s and the 1960s, making primarily Aluminum bodies for OSCA. Of the some 200 cars produced by OSCA, perhaps 80 were MT4 models, and of the MT4 models, records show 40 Spiders with Morelli of Ferrara bodies. All five OSCA FS 372 Spiders (an updated version of the MT4) were bodied by Morelli.
