This is a new acquisition. It is not a Willys "M" Jeep, but it is a legitimate post war Willys Military Jeep.
It is also the Father of the M38. Features developed for this jeep made it to the M38 while others were discarded. The "U" in the type means underwater and that they could do.
Interesting bit" The early starter for the M38 made its debut in the CJV-35(U), but it was wound for 6 volts.
