There is a small gold – colored metal tag, 14x34mm, riveted to the top of the filter mounting bracket. I have seen different patterns of these tags; this is a perfect duplicate of one. F.I.S.P.A Fuel Filter Housing Tag
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 (A) 24.8x46mm, hole spacing is 21x41mm, Weber script is 5mm high.
The 250s used a German Z.F. steering gearbox. This is a small, black metal tag, 20mm X 50mm that identifies the pat number and serial number of the steering gearbox. This one is a duplicate from a tag on a 250 Short Wheelbase Berlinetta. Z.F. Steering Gearbox Tag
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. Shell Oil “Super Shell Motor Oil” Tag. 70mm x 25mm for Late Daytonas
