Identify the Front Hub

[Racerbvd]

As I go through my decades of Porsche "Stuff" and trying to sort everything out, while matching up hubs, one is slightly different and has no part numbers

Any ideas or thoughts?

Tom made this nice comparison of hubs, among many other comparative pictures he has done.
