Hi,
The show dragons have distrinctive identification.
First, the door post serial number will start K530 followed by an "X-" with a single digit number; the highest known number of the group is X-6. The larger firewall body tag will have 999 and 888 for paint and trim numbers along with a number beginning with K-at the SPEC-FO heading. The smaller firewall body tag may start out K5311 or K5321 rather than K5301 but a K5301 is not a show stopper.
Also, be advised that the "6-pack" seems to have already been accounted for. One went to the wife of Brooks Stevens, the Milwaukee WI based Industrial designer. My father owned one at the time of his death; it has since gone to ground. Jerry Johnson in IL owns perhaps the best of the group, and the Buchinger family owns another. One was supposed to have gone to Bob Smith, one of Milwaukee WI's K-F dealers (the Alice Stevens car was delivered by De Boer Motors, another Milwaukee WI K-F store) and the last was supposed to have gone to Hawaii, assigned to the Henry J. Kaiser Corporation pool and later returned stateside. However, it is possible that some of this may not be correct or the car could have migrated over time. Further, additional cars could have been produced matching the color, trim and equipment of the original show Dragons.
If you want someone to look at it, I live in Rocky River just a bit off I-90 near the Clague Road exit (west side of Cleveland OH).
