History Finned 4 to 2 barrel adapter

Just picked this sweety a couple of days ago. Finns are 3/4” deep and has the initials FS inside. Any collective hamb knowledge to history ? One of a kind or ? Thanks

 

Something from San Francisco.. not from Clifford for sure. O’Brain made a lot of stuff. Offy made a lot of adapters too. Might have been when small base 4 barrels were the norm in the early to mid 50’s

 

It's strange the way it's scooped out for the studs. Are they splined wheel studs?
It looks a lot newer than the intake. But I'm not knocking it 'cause it's a cool piece.

 

Thanks. I have always been interested in speed parts and their history. This is going on on my inliner six , so one more piece of the finned parts puzzle I am collecting.

 

The studs sort of a pressed in look to them .

 

Original intent was for folks that thought a 4 barrel used too much gas, so if they stuck a 2 barrel on this thing, their mileage would increase. The same adaptor was used by kids that couldn't afford a four barrel intake to screw a WCFB or 4GC on a 2 barrel manifold.
Result in either case were usually more trouble than success.

 

I have an addiction to old parts so I cannot pass up much . My plan is to get something finished up for my project. This one is more a cruiser than a bruiser . A 1948 Ford F1 , that I figure to use as a daily driver. So , I have plenty of different cfm 2 and 4 barrel carbs to experiment with . Future project is a 1936 Plymouth coupe with a little more ballsy six with a 3-71 blower.

 

I have see adapters other way around from 2 to fourbarrel carb.

 

Vintage speed still makes adaptors like that. I just bought a set from them. Almquist Engineering used to make em and Honest Charley Speed shop used to sell em too.

 

I have had an Almquist and a couple Vintage Speed ones as well but this one I never seen before. Thought the deep fins , finishing details and the stamped initials piqued my interest in if there might be a history for note . The studs are pressed in from the bottom and outer holes are a dead match for intake bolt pattern. I was just wondering if it was an obscure aftermarket piece or what the initials stood for .

 

It has the looks of a home made casting. The fins, while decorative, add some rigidity and also keep the casting thickness fairly even. There is no spot facing on the bolt holes or where the studs seat. The "machining" on the flat surfaces looks like it was done with a piece of sandpaper glued to a piece of plywood.

 

I like the unusual so it’s a keeper .
