Keep in mind: MacGregor's last year as a supplier for MLB flannels was 1967. There were a few MacGregor jerseys that were carried over to 1968 (White Sox roads in particular, as team ownership was incredibly frugal about MLB level unies in that era.)

MacGregor's name did not show up again in the 3 major sports until their relationship with Sand-Knit began in 1985. There are a number of jerseys in the transition period in MLB, NFL and NBA that may show one of the 2 tail tags as MacGregor Sand-Knit and the other as Medalist Sand-Knit.
