Thanks in advance,

That's a Franklin intake manifold. Swan made the intake, but the exhaust/gas heater (aluminum casting) is Franklin. The pipe is part of an electric primer from the solenoid valve on the manifold down to an electric heating coil primer attached to the fuel bowl of a Stromberg carb, ether an OE-2 for 1927 or a T-2 used in '28.

 

Here's a picture of that same type of manifold, gas heater, and primer tube on a '27 Franklin Series 11B.

 

The one you have with the shorter rear exit from the exhaust gas heater is for '28 Series 12. It still has remnants of the potmetal T-2 mounting flange used in '28.

Thanks, you saved me a least a hundred hours of research. There are but a few contemporary snippets about marques that claimed to use the Swan system as OE: Auburn, Elcar, Franklin, Gardner, Kissel, Stewart, Studebaker & Rickenbacker. 

 

Impressive knowledge base here.

 

Thanks again

The number 35083 on the exhaust gas heater is the Franklin part number, which is also the factory drawing number. I looked up the factory drawing, and it lists that used for 1928 Franklin Series 12 and 1929 Series 130. The early 130 also used a T-2 carb so it could be from either year.
