The original units were made by Grant. They were black in color. Grant used to advertise in the '69/'70 mags of the period and showed their CD boxes and helmets in the same ad. Joel probably bought the Grant units are "decalized" them which he did on all his parts. Jacobs maybe using the original tooling as these companies may have sold off their tooling. Jacobs have only been around for 25 some years at best.
