The Philadelphia College of Osteopathic Medicine does not appear in early IBAC lists from 1927 or 1948, so the IBAC may not have assigned the college a hood lining until the late 1940s or 1950s. A list compiled by Kevin Sheard in Academic Heraldry in America (1962) described the college’s hood lining as maroon with a silver gray chevron, which was also how it was described in IBAC lists from 1969 and 1972. “Silver gray” was how the IBAC described a satin lining fabric in a light shade of gray, which was used for institutions having either light gray or silver as a school color.
