History Old headers

I got these headers with a 57 Corvette project and I am trying to identify them.
I believe they may be Hookers but the only marking on them is pictured.
They were purchased late 60's or early 70's.
The primary tubes are a hair under 2" and the collectors are 3 1/2".
Pipes were added to connect to the Corvette exhaust system.
Any help identifying these is appreciated.
Thanks, Bruce B

 

Could be Hedman's?

 

I had a set of chrome Hookers and they had a plate welded on that said Hooker....

 

Bruce my guess would be Tubular Automotive out of Rockland Massachusetts. Somewhere I have their contact information but you could look them up on the web. They have made headers specifically for these modified Corvettes since the 60s, both big and small block. You can see their name on Hayseed's rocker. I have a set on my avatar car and the primary tubes are about the same size (although it is a big block). Baron who is building a 57 Vette drag car and has a build thread on the HAMB, I believe had them make a new set. They are really great headers and the sound is second to none (except for maybe 180 degree headers). You may send them a photo and see if they can identify them. Jim

 

I spoke with the guy I bought the 57 Gasser project from and he finally remembered that he had them made by JR Headers in Michigan.
He then had them plumbed into the Corvette exhaust system and chrome plated in Dayton, Ohio
JR was later bought out by Headman.
