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. Voltage Regulator Decal 1R19B probably P.F. Cabriolets & similar Scaglietti cars.
