Wanted info on Rare Flathead intake

My brother inlaw gave me this manifold for doing some work on his Model A
My Father inlaw got it back about 60 years ago. We live in St. Louis, but he was Tenn. Don't know if there was a speed shop in Tenn, that had some of these made. I would like any info. on any history of Jet.
Thanks, Jimmy

 

If you orderd a quanity of manifolds fenton would put any name on them.

 

when Fenton gave up their patend rights to the intake, there were 35 companys that produced the copys of this intake most only makinf a hunderd or so, I have have one that is from D&S......

 

What part of tennessee? Flathead Charlie's has been in business in Chattanooga for a long time. They probably sold parts from everyone who made them at one time or another.
Y'all have a good day, Keith
