Screen grab from a 1950 movie, I don't know if it is a Red or International but the trunk added to it is nicely done.
Looks like someone took the back door and maybe a bit more out of a big 4 door and moved the whole back section forward to make a wrecker out of it. It was real common back then to take a big old luxury sedan and cut the back half of the body off to make a wrecker out of it.
Freaking awesome. I know where I can get the wrecker stuff. The fabrication part would stop that project.
Tow coupe ? Coupe truck ? Troupe ? Coruck? No clue what you call it, but I call it cool. Would love to see more pics of it
