Pair of 6 cyl intake/exhaust manifolds c/w carbs, what make/model

Top manifold looks like an exhaust,  with a thermostat control as used in the '30  40's.

 

Lower manifold is quite old, likely late teens to 20's.

 

carburetors appear to be Marvels. fron late teens to 20's, with heat pipe connections.

Can you find any numbers on the castings to help

I'm assumed these came from same engine, the upper one is exhaust, and has a bolt on gadget bracket? on one end, and a close-off plate at other end (perhaps for a add-on manifold heater?). The lower intake manifold mates up to the carbs correctly. Carbs are Marvel units, each noted as J2H, and have further markings such a C, A2, and Y. Based on a previous post about Marvel J2H, these could be circa 1920 Buick or an industrial/tractor application (thus cast iron versus brass on some pieces), and intake manifold looks near identical to 1920 era Buick. However exhaust is not 1920 era Buick, so the 2 manifolds may be from different engines. Hope this helps.

The lower manifold looks like the last version of Buick's cage valve 6 , 1923. The mounting bosses are for a Stewart vacuum tank. Both the carb's also look like Buick. The upper manifold with the rusted baffle and what looks like a generator mount  is something I have not seen before, not Buick 6. Buick uses an exhaust with 6 port runners and exits at the front of the manifold. Also has a corresponding flat surface that allows heat transfer between the exhaust and intake manifold> In addition  a small tube that takes exhaust gas and flows it right through the carb, that small connection on the carb body. Fuel needed lots of heat in the late teens / early 20's.

Thanks Greg, here is photo from a previous post showing a "1920 Model K46 6cyl Buick" and similar Marvel J2H carb with similar intake manifold. As you note, exhaust manifold is different entirely for this car. Vac tank is shown as you describe. The gizmo bolted to top of exhaust manifold in original posting is puzzling? Don't think anyone would mount a generator there, lot of heat and would not want excess vibration etc, plus size of mount is quite small. So remains a mystery as to what it is. Equally puzzled as to what the tin baffle/cover plate was closing off. Almost looks like there may have been an exhaust cross-over pipe for an early V6? later converted to dual exhaust? Just musing here!
