1955 Kaisers could have a few things going for it that a 1950 Kaiser would not. First, the general history of the 1955 is that it's the last model year for the regular production Kaisers. Second, only a handfull of 1955 2-door models survive. In contrast, somewhere between 10,000 to 20,000 Kaiser and Frazer cars were re-tagged as 1950 model year cars. There were a few thousand or so (all makes and models) built during the "regulation" 1950 model year and most of these were Kaiser Special 4-door sedans or Travelers built to dealer or distributor order.
There are two ways to identify a 1950 that is retagged versus a legitimately built 1950 model year K-F prouct:
1. The serial number was not changed on the door post tag; only the prefix. We can identify how many cars were built prior to November 4, 1949. 1949's unsold at this point were re-tagged 1950 models. As the break-out I have is by make and model, we can work the figures to find out what month a car was built even if it is a Kaiser Traveler, Frazer Manhattan sedan, etc.
2. Body tag numbers on the re-taggs were normally unchanged. A 1950 door post tagged car with a 1949 model year body tag is also a leftover 1949 vs. a car built during the 1950 model year.
