Old Accel distributor 37300T

I am about to breath new life in this relic. Its a Billet duel point distributor from many years past. Being a Tach drive, I plan to use this with a old Moroso mech tach, for the Nostalgic look. Petronix makes a conversion part# AC-182A, to ditch the points for electronic breaker-less system. Has anyone used they're products before? This one in particular? I would like to know some details about this old thing, but searching the internet and Accel's website draws a big zero...It feels like it has some mech advance, or maybe its just worn out , but I don't think so. Can anyone shed some light on this old race distributor?
