I am trying to put together a timeline/chronology for the different iterations of the Badman kit with details to better identify and date them. I know a few things already but there are still some shady areas. For example, I have two that seem to be first runs of the kit circa 1970, but they bare different numbers. 6747 which is a Mattel reference number, and PC229 which is a MONOGRAM number. Boxes are otherwise identical, and not 90s reissues to my knowledge. So, which came first? And in what year, 1969 or 70? Any info would be greatly appreciated.
