Just make one. Start with at least .090 brass, cut it out with a jeweler's file, clean it up and final shape it with a fine file. Try a #6 blade or coarser...something with some bite. That will take less time than writing an order letter and taking it to the post office, and much, much less time than trying to get a commercial piece to look right. And no wait time, backorders, incorrectly picked part, or postage.
