Mid twenties sumpthinorother, mid to high grade car, Stewert vaccuum tank 6 cyl, may even be early twenties by the looks of the grab handle, looks like brass. Cant quite make out the dust cover cloisonne, I would guess 22 or 23, nope I could be wrong, it has vacuum wiper motor so it may be 25 26 or so.
Almost looks like a B, maybe Buick ? I am not familiar with much other than Dodge
