Ferrari had a long relationship with the Shell oil company. A lot of the early cars had some type of metal tag in the engine compartment specifying the type of Shell oil to be used. 212 E-1 Shell Oil Tag, 100mm x 60mm
The early racing cars used an aircraft rotary fuel pump. These are seen on the TRCs, Testa Rossas and the Maseratis from the 1950s and 1960s. These tags were screwed on the front surface. The dimensions are 43mmx43mm. FIMAC Fuel Pump I.D. Tag.
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 (C) 24×45.7mm, hole spacing 21x41mm, Weber script is 6mm high
The Dunlop master cylinders had a small plastic “zip tie” parts tag embossed with the part number and the date of manufacture. This is a very detailed reproduction of a 275 GTB original. Dunlop Master Cylinder I.D. Tag
