Can’t say that I’ve ever heard of a “Willy X Jeep”? Looks like a plain old CJ-5 to me.

“This is the nicest and most original 1960 Willy X Jeep you will find under $25,000. 6592 original miles. In 2012 @ 2346 miles a complete rebuild was performed on the entire vehicle, costing $11,000. ALL receipts for the rebuild on hand as well as original jeep documents. Everything on the Jeep works as it should. One light switch knob handle is broken. Little to NO rust, tires are in great condition, 4WD works as it should. It is a one of a kind Jeep. You would have to pay $25,000 to come anywhere close to the quality and collector value of this jeep. This is not a Jeep to slap big wheels on and go mudding. It’s just a pleasure to own this piece of history. I have enjoyed owning this Jeep but as with its second owner, it is hard on my back. I am the 4th owner. You could take this Jeep to a show as it is.”
