Distributor question

[daddyg]

I have a distributor that I pulled out of an old Bronco that I bought. It's a dual point Motorcraft with the part number 12127 E. It only has mechanical advance and it was in a 302. I figure this originally came out of a Mustang. Does anyone know anything about this distributer? What kind of car it came out of? Is it worth anything?

Thanks in advance
