Technical cast iron 153 ChevyII exhaust manifold

For a time there was one on ebay which was a new casting. Any idea who this is? Thanks.

8-10 years ago, the owner of French Lake Auto Parts said they once had some ''hard to find'' Chevy manifold recast. I could be wrong, but they might have been that Chevy 4 cyl. I don't recall if he said any more would be made. I think they ordered 200 of them, and many were already sold by then.
