We all know that Sir Paul McCartney has used LaBell flats, and Pyramid Gold Flats, mostly on his Hofner. But, does this picture suggest from the red silks that he's also used Thomastic-Infeld Jazz flats?
LaBella had red on their flats for a while, and PMC did use them for a few years. Since the early 2000's he uses Hofner (Pyramid) flats only on his '63.
