Found this pic, interesting?
Hard to tell from the pic, is it a toothed belt?
Someone was making and selling belt driven distributors years ago but I forgot who made them. Someone in California, I think. They show up on cars every once and awhile.
Jess Blaker or one of his buddies in Turlock CA were the makers of these. Quite a few cars that were built around that area had them as an alternative to the poor quality aftermarket distributors available at the time. They were pretty simple- a flame cut bracket, a Vega distributor, two timing belt sprockets and a timing belt.
Simple and effective. I like it.
