I have just read through "Identifying Unmarked...BSR" and am wondering if all BSR handles have what I can only describe as sort of an elongated scoop-out around the elongated hole, rather than just an elongated hole...? (Hard to describe....) I've never seen one or a picture of one that didn't, but was wondering if there were exceptions.
