I was searching something and came across an old post on changing the direction of wind on medalists.
Richard Komer when explaining it and said this…
"Flip the drag disk over and slide it and the metal retainer back on the shaft. If the drag disk is beveled, it is not reversible and you will not be able to flip it. "
Richard or anyone…[I have not happened to have seen a drag disc that couldn’t be reversed…I’ve changed quite a few…none that old]…so does that mean the periphery/ edge of the disc is beveled?..I assume you don’t mean the notches?
