Concur with the BB line of reasoning. However, my 49 216 actually had 2BBs embedded that provided a perfect little white static blip on either side of the pointer when dabbed with a little white paint. However, it took a leap of faith that they existed when I was dabbing the paint because they are very very subtle without any highlighting. They appear to be spaced perfectly so that they show up on either side of the pointer when its timed properly.
