I believe that since it does have a back door, and obviously its too short for a coffin to be slipped into, then its best use could be a flower car. It would be excellent for that use. It does look like it could have a middle door on the right side of the car. That gives the driver a wider door on the left to easily slide in and out of. The right and back doors (?) to load flowers We had a glossy black 1930 AA hearse at the Oak Harbor mortuary when I was a kid, and the hearse was based on the AA chassis with wire spoked 1929 20"wheels on it. It looked really sharp to me. The AA hearse was plenty big for any coffin to be slid into with room to spare. It was a sad day when my neighbor chopped off the body and made a flat bed truck out of the 1930 AA Ford hearse.
