Jim Betts,
Although I am not the person to ask for details on Jeepsters, there were 1949 and 1950 models as well as the 1951's and some were 4 cylinders and some were sixes.
Your list may be more detailed than necessary. Can differences between models be discussed within the year/model data record? Unless we need to break-out 2-door from 4-door, I suggest combining them. Also, in 1954 several cars were available with different engines and became, for example, Eagle, Eagle Deluxe and Eagle Custom. Do these need to be broken out or can the differences be explained with one data record?
Also, Larks were "KA2" in 1952, then "KA1" or "KB1" in 1953, then KB1, KA2, KB2, KA3 or KB3 in 1954 and on top of that, in the 3rd series '54's there were two separate runs. Larks were also 675, not 685 in 1952.
Missing is the 1953 653-RB1 675 heavy duty taxicab; 1954 654-RB2 675 heavy duty and 1954 654-RB3 685 heavy duty. There was no 654-MB3.
You also left out a few models in 1954 and 1955. Check out the production figure list on the Willys Aero website listed below my name for references, especially when it comes to Deluxe or Custom in the model name. Any models with a 5000 number serial range in 1954 did not have a "Deluxe" or "Custom" in the model name or as chrome script on the car. The 1954 break-out on the list came from a specific factory document showing high serial numbers for all 1954 models.
Also "PC" just stood for "passenger car" as opposed to the Jeep or commercial line.
Rather than bore the club with all this minutiae, we can probably fix all this in a few emails. Thanx for all you've done, all you keep doing and all you will do in the future. Excellent!
