I have seen you state the belief that there were no 2As produced in 1949. I find this data much more consistent with the service bulletin information as well as with what we know about the average production rate over the life of the 2A. Also, I added the computed "Quantity" column (also off by one for 1947). It does have an obvious error in the ending SN for 1947 that should be one less based on all the other information we have. Here is the production data from the first edition of the Willys Master Parts List, 1950: At ~204 per day, you could easily produce #224764 before the end of the calendar year. This would be from bulletin 48-60 showing # 215648 was produced on. The same thing happens if you examine the last serial number/date combination in 1948. Using a number of 210 vehicles a day (the estimated rate of production between September and October of 1947 and consistent with the early 1948 production rate BEFORE production tapered off at the end of 1948, you get a last serial number of 161044 that makes much more sense. If you extrapolate production for the remaining 70 days in 1947 at 195 per day, you go well beyond 148458, supposedly the SN of the last 2A produced that year. The last serial number/ production date combination listed for 1947 is #146344 on. )Įven using lower than overall average daily production figures, look at the conclusions one can draw from your bulletins. Perhaps one of the numbers were copied incorrectly or entered that way originally.
This data suggests that only 256 vehicles were produced from mid February to the 3rd of March when we know that is a bit over 1 day's typical production.
( - As an aside, I think the production figures for 1947 were higher than I computed because I think the serial numbers or dates for the the first two entries for 1947 don't fit the other information very well. I came up with 195 per day in 19 and 204 per day in 1948. I made a few computations of the average number of vehicles produced each year based on the first and last dates for changes having a serial number listed in your list of changes by serial number and production date. Sean, I think you are overlooking the information that can be derived from your own service bulletins. The usual "yearly" numbers correlate well to numbers w/dates in the service bulletins, with the exception of 48/49 transition. I believe these are "calendar" year production numbers, not "Model" year sales numbers. The "history" figures were culled from yearly figures such as posted in the manuals.
