Stop in for a cup of coffee

I have an odd distributor,im suspecting its for an industrial application. For a 318.
No advance. No vac can and no mechanical. I have no idea what its from. But it is electronic.
Was gathering parts,doing inventory of sorts and came across it.
I have 5 alternators to choose from. Maybe 6. Gotta trudge out into the great white yonder to check. Only 1 starter.

Thought i had a pile of water pump pulleys,no luck so far.
Small diameter deep pulley,
Guess im cutting and welding. Easy. Trash an old pump to make a jig in the lathe.
