That looks very familiar. I thinking a broken piece of a ford distributor, on the side where the cap snaps on. As part of the casting, it would say "Autolite". The FLOR is cast intot he body and next to it is an area that would have the remainder of the part number stamped into the body. Or it could be a tag that would have been riveted to the distributor body. I am not able to show a picture at this time - will try to post later with one. That's my input . . .JH
