Distributor Identification Question

Can anyone identify a distributor by a number stamped on the side? Distributor is a single points unit that was on a 1967 318.
Only number I can find is: 2975334 1 8 stamped in the body.
Also there is the number 36 stamped in a couple of places. There is no manufacturer name or logo. If there was supposed to be a tag or sticker, it is long gone.

Anyone have any idea what I have?
