Help with intake manifold identification

[Dusty Dude]

Hoping someone can help me identify who made this intake for this 67-75 era 318. It has no markings anywhere and I have not been able to find another like on the internet. Belongs to a friend who just bought a bunch of stuff from a guy who inherited some property that is covered with all kinds of stuff and he just wanted it all gone dirt cheap.

Any help would be greatly appreciated.

Sorta looks like an LD4B. But I don't know. Hard to see in the crusty photo, is it iron or aluminum ?

It's aluminum.

Looks like an LD4B with the letters/numbers ground off.
