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.
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
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
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.
