My guess would be a repurposed WWI ambulance in Europe.
It looks like a "Peerless" radiator shell. Peerless made a lot of after-market parts for model Ts including honeycomb radiators. I don't know if the shells only came with the radiators or if they were sold separately? I have seen many of the shells usually without the radiator. I have seen ads for the radiators showing the shells on them.
There are several variations of the shells, in both low and high radiator sizes. Most of them have the "Peerless" name stamped into the front panel. Some have a sort-of "double diamond" impression stamped into the panel with a soft-metal casting riveted into the impression. In my over 45 years in this hobby, I have only seen one totally intact such shell and a couple with only half of the soft-metal casting. I would guess that they may have been sold with other names also on the casting.
Peerless also did sell replacement radiators in brass era size and shape. I don't know how early these came out, however I have seen ads for them as late as 1922. I know a couple people using these on brass era speedsters. They seem to cool very well.
That picture is interesting. The chassis is long. It looks to be longer even than a standard TT. Yet it has an extra long side apron and running board as well. The rear wheels look more car-like than TT to me. The front end appears to have Hasslers.
Very interesting.
Thank you Herb!

I first thought it might be an armored vehicle.
I'm thinking that it's somebody's canvas covered camper for hunting trips. The windshield obviously has some streamlining ala late 1930's. Aside from that it looks like something you could take out in the sticks and live out of for a few days.
It does appear that it was a car originally because it has skirts along the sides and trucks had a short step only. I would presume it was used by a religious group, possibly a handy parishioner lengthened the frame and built the body. They took their religion pretty serious in the day and this vehicle has all the earmarks.
