1925 Chandler in Marshfield, WI

[Hudsy Wudsy]

There is a 1925 Chandler for sale on C/L in WI to which I will share a link. I mention it for it's own sake, but especially to ask you guys to speculate about the device under the hood. It's near the carburetor, on the driver's. It's purpose could be twofold, having something to do with fresh air intake or maybe a heater for the interior. I could try to speculate, but I think that I'll enjoy listening to you learned souls explain it to me:

Looks like a home made hot air heater to me. I do not see an outlet in the passenger compartment photos. 
My Model A has an accessory hot air heater which works excellent.....extends my driving season, especially with the Mrs. along.

By the way, the Chandler is a neat car and very worthwhile - has a lot of potential in looks.  I would probably do a little customizing though and relocate the spare tire from the rear mount to one (or two) sidemount(s).

My reference list the 1925 Chandler Model 33 as a 288.6 ci L-head Six.   Looks like an OHV by the photos.

Yes, I agree I meant to take a close look at Buick sixes, but forgot. It's a transplant for sure.

Sure looks like a 1926 Buick Master engine. Just missing the spark plug cover.

I have to admit that I don't have a clue as when hot water heaters became the norm. I suppose that basic water pumps, like this Buick engine had, weren't necessarily enough to guarantee system wide circulation. The scavenged heat off of the radiator must have come out through a vent under the floor somewhere I suppose. It looks to me like a pretty elaborate set up, but it was Wisconsin car, so any heat is valued greatly. I wonder if it wasn't home made?
