P4 replica origin?

While browsing the net, I ran across this P4 replica. Perhaps discussed before, but I don't remember it. The body is made of aluminum. All the replicas that I've seen have a fiberglass body.
Anybody have any idea who made the aluminum body used in this P4 replica?

And here is a duplicate chassis to the above car. I noticed that the builder has some sort of massive jig to build the frame. Looks like a major effort was spent to duplicate the chassis. How does this chassis compare to an original P4? Anybody have any idea who the chassis maker is? These links are to the seller of the cars. But probably some other secondary party is actually in possession of the jig and still able to make the chassis.

It doesn't look like your basic NF Auto replica. The chassis tubing is round in the photos that I see. So who is cranking out this/these cars?

Since we have no seperate section for replicas, and the Vintage section gets antsy any time the word REPLICA is used, this seemed the best place to post.

 

They seem to be rather popular to build.....

last time I saw a Norwood alum P4 it was around $300k

1st ones had a TR engine, later models were supposed to have a replica V12 as well
