Default Federal double tone sirens

In case you're not aware of the differences in these:

76 = painted for concealed mounting (painted base, two hole mount)
77G = chrome for exterior mounting (chrome base, four hole mount)
77L = chrome with stationary light in front (too long for mounting behind the grille)
78 = chrome with moving light in front ( " )

A suffix = no brake
B suffix = brake
R suffix = rear flasher

All of the chrome versions were available with flat or curved mounting bases, permanent or demountable.

Photos of each model can be found online.
