Technical Mystery Olds Rocket dual quad manifold

I picked up this dual quad manifold for a '49-'53 Olds Rocket last week for a good price. On looking it over, I can find no markings of any kind. It is aluminum and uses the old "Square" base carbs (early 4G's, WCFB's, Aeroquads, etc). Surprisingly, it has no provision for exhaust heat, which indicates to me it must be early. Does anyone have an idea of what it is and who made it?

 

It is an Offenhauser, I had one just like it years ago, someone has removed from the water crossover.

 

I am going to agree with @Moriarity.

It looks more like the Detroit than this picture of an Offenhauser.

Idk but it would look great with a finned valley cover beneath it.

 

Detroit Racing with out the script..
I have a similar Cadillac.

 

I gotta agree with @Moriarity and @42merc on "DETROIT" based on the linkage mounts and "RACING" rather than "SPEED" because of Mark's manifold and the lack of exhaust heat). I have to admit the Offenhauser looks very similar; perhaps there was some "Cross Pollination" way back when. The center "ribs" substituting for the heat riser channels look a lot alike.

"The Power of the H.A.M.B." (Let's see, it took all of 95 minutes). I'm gonna double check the edges for evidence of removal of the name, but if they did take it off, they did a hell of a job.

Thank you, Gentlemen. ( I have been doing this for almost 70 years and have never heard of this brand.)

 

Detroit Racing intakes were some of the first aftermarket speed equipment for the new OHV V8s. In fact, they started out with dual 2 bbl. manifolds and then progressed to dual quads.

 

Dual two's are pretty cool also.....
