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.
These are aluminum tags that were used on the early 1950s cars. The reservoir mounting bracket had four tiny slots and the end tabs of these tags were inserted into these slots then bent to hold them in place. The brake fluid was very corrosive so few of these tags survived. Early Brake Fluid Reservoir Aluminum Tag.
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
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
