It could just be my imagination, but that body looks like it could has more of a swoop for the passenger entrance similar to a pre-MB.  This is worth a closer look.

“I have a 1941 Jeep Wheelies that runs great. I have stored it in my barn for years and used it for Deer hunting. I need to clean out the barn. I do not have a title for the Jeep. I have sold my second one a few years ago without a title and the individual did not have any issue gettting one. This is a really good running Jeep. Do not call before 11:00 AM CST please. 417-226-4500”
