Can anyone tell me who makes this header ?

It came off a 2 owner '73 Datsun 240Z that I'm getting a 2.8L motor built for. The 6-2 connector is a little beat up due to ground clearance but I'm thinking about getting it bead blasted, painting and wrapping it to save a little bit of money.

I'm also toying around with looking for a used Stahl 6-2.
