Weber carburetors were made in Bologna and were used on “all” of the Ferraris from the 815 and 125s through until the 512BBs. There are photos of T.R. #0666 and the four cam 290/315/335s with Solex carburetors but Webers were the norm. The really early carburetors had beautiful little cast brass tags, but Weber soon switched to the more conventional aluminum tags with the black overlay. These tags were attached to the carburetors with small u-drive rivets. Tipo (A) 24.8x46mm, hole spacing is 21x41mm, Weber script is 5mm high.
