This may be a 1949 CJ-3A with a convertible DJ-3A Body and windshield. Whether the chassis is DJ-3A or CJ-3A isn’t clear to me.

“1949 Jeep Willy cj3a 4×4 Does run and drive. Has good tires. Brakes have been upgraded to disc brakes front and back. Body is in great shape. Has the original straight flat 4 cylinder. 3 speed stick shift. Would make a great off road 4×4 Have a clear title”
Without a serial number it is difficult to tell what it is. It does appear to have a DJ3A convertible body, sitting on a CJ frame or a DJ3A with CJ 4×4 axles under it.
