Chris shared this link. The flattie is listed as a 1951, but appears to be an early CJ-2A.
“I have for sale my 1951 and 1961 Willys jeeps. The 1961 runs and drives great, starts every time but the 1951 does need some work. The 1961 jeep has 10000 miles on a complete rebuild. They are both original.”
