I was told that it is for a small block ford and that they were manufactured in the mid 60's through the 70's and were sold through Carol Shelby and hot rod retail "Speed Shops" and mail order. Also, was told that unused genuine vintage cobra parts are quite rare and valuable.Considering that this is your only post you should provide more details or else everyone will think you are a fraud. What size engine is it for??
You'll likely need more details & some pedigree if you hope to realize a big $ sale. Was British Motors Beverly Hills in any way affiliated w/Beverly Hills Motors? IIRC, that was the name of the outfit run by a fellow named J. Brunck(sp?), who teamed up w/Shelby in the 80's to build the "continuation" '66 GT350 convertibles. They by necessity had to tool up a lot of repro bits for those cars, & I believe a lot of the excess was sold over-the-counter. As I say, you definitely need some provenance to establish the credentials of that intake. Experts chime in, please, as it has been a while for me, but didn't the original Cobra valve covers & F4B-style bear Buddy Bar markings in the castings? Were the Weber intakes sourced from Buddy Bar as well?
I really don't know if there was an affiliation. Unfortunately, my step father, who purchased the inventory, passed away from cancer a few years ago. For some reason, he held onto this manifold and didn't sell it along with the rest of the inventory. My mother only remembers him saying that it was an original intake from the 60's and that it was worth at least 2K. The only other manifold that I have found like it was a set up that a guy sold for $5,500 last year.
Not to be too Nit-Picky but....
You describe it as a 2 x 4 manifold (I always thought meant two four barrel carbs).
Shouldn't it be described as a 4 x 2 (four two barrel carbs)?
Good Luck on a quick sale, it looks nice and would look even better in a car.
