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 MO 100 Tag. 70mm X 25mm. For early Daytonas
The 330s and 365s used a Borg Warner “York” air conditioning compressor. This is a 42mm X 40mm aluminum parts tag for the compressor. York Compressor 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 “Clam Shell” type jacks were supplied with the “inside plug” 250 series cars. A drawing of these jacks can be seen on page 256 of Richard Merritt’s book Ferrari: Operating, Maintenance, and Service Handbooks 1948-1963. The jacks had an A. Rejna metal tag riveted to the top casting. The original tags were either red or green. Red A. Rejna jack manufacturer’s tag.
