If you mean the reddish distributor body and cap they were offered years ago by an aftermarket supplier. They are hard to find these days. Some folks have claimed they are early 1928 but I believe that claim is not true.
The Mallory dual point distributors that I got at Berts have red modern style distributor caps . There were some reddish colored original style caps with Ford script that were offered back in the day by the aftermarket .
