I’m not sure what a GE refrigerating machine type CK-2-D16 is?  The seller lists this as a CJ-2A, but I’m guessing it is a M-38.

“I have a 1952 CJ2A Military Jeep with trailer for sale that I have owned for 35 years. It RUNS GOOD, is in good condition, no rust and could easily be restored back to military standard. It also has an operational general electric refrigerating machine type CK-2-D16 serial #8213178. I am asking $4,000.00 for the Jeep and trailer, please call Wayne at 512-970-4901 with questions.”
