It certainly looks like a later KH Jeep wheel to me.
Jeep used well over 20 different variations of KH wheel from 1945 through 1971 alone.
This appears to be a 1960's wheel.
Does not appear to have a HD "6" gauge disk.
Perhaps its a 5.5 x 15" CJ wheel..... I can't tell without more detail.
Is the rim welded to the disk ?
Can you thickness gauge both the disk and the rim section ?
If you can measure it, then it will also be nice to know the rim width.
If you cannot measure the rim width with tire on then measure distance from outermost rim edge down to the WMS.
I expect I can figure the actual rim width from that measurement.
