It could be an Austin but from the looks of the caps and tail lights it sure appears to be a 30-31 Ford Model "A" Fordor that has had the rear doors sectioned out and moved forward if you look as close as you can the roof lines give it away....or so it appears to me.
No. Window sills are a long way from lining up. Door windows are square. Rear quarters are rounded. Rear crown is too short like it was cut to match front. Two different car pieces.
