These are reproductions of three different voltage regulators from the late 1950s through the early 1960s. The decals are mounted so that the top of the writing faces the bottom of the mounting surface as the regulator is attached to the electrical panel. The voltage regulator information is not contained on the build sheets and the changes were probably made by Pininfarina to adjust the electrical system to the additional electrical equipment of the later cars.

In 1959 Ferrari began production of the new 250 series “outside plug” engines. These engines had the spark plugs moved from the center of the engines to the lower side of the heads near the exhaust ports. At about the same time Magneti Marelli supplied a new series of red coils. These coils were in two configurations. The earlier version used a small tubular-shaped resister that resembled the American “Tootsie Roll” candy, hence the nickname “Tootsie Roll” coils. These were used as late as the early 250 GTEs. The can, bracket and the resister were painted red. The second series used a square-shaped ceramic resister. These coils were painted red along with the ceramic resisters. I believe that both the cans and the square resisters were painted the same color; however, over time the resister color might change a bit due to heat build-up. The coils with the square resisters had a separate mounting bracket with the bracket, pinch bolt and nut, and mounting screws plated with silver or white cadmium. The square resisters had the ohm rating silk-screened on the top surface. Both of these coils used a truncated oval Magneti Marelli foil sticker located 1/4″ from the bottom of the can on the “front” surface centered in line with the resister. The changes in pieces like these, which were supplied by outside vendors, normally did not coincide exactly with Ferrari model or yearly changes. The records of the timing of these changes are sketchy at best so teh restorers and judges are always looking for original components and photos to try to document the timing of the changes.

The early cars were equipped with the old-style lever action shock absorbers. Prince Bernard of Holland was an enthusiastic backer of Ferrari and was probably the force behind the switch to the Dutch “Koni” brand of tubular – type shocks in the early 1960s. Ferrari also used Allinquant, Miletto and G.M.F. shock absorbers, but most of the cars had Konis. In 1974 Koni switched to a later type of decal with an orange shock absorber on a white triangular backgroudn. Koni wing/shield shock absorber sticker
The rectangular foil coil stickers were used on the late 250 GTEs and Lussos from 1963 on through the 275s, 330s, 365 single-cam cars and even the early Daytonas and c4s. The stickers were positioned 1/4″ from the bottom of the can in line with the center of the resisters. I have seen rectangular stickers that looked like they were printed on gold foil. These may have been an earlier reproduction, or may have been discolored due to the oily vapors and engine heat or may have been originals. Rectangular Magneti Marelli coil Stickers.
