There are two main varieties of Past Master products, those with the compass, quadrant and square and those with only the compass and quadrant. Some jurisdictions reserve the former variety for Past Grand Masters while other (most) jurisdictions allow either to be used for Past Masters. Search for the squareless tag to just see the second variation. We also have an entire department dedicated to Past Master regalia.
