I know I've asked before but now I have something to compare it with. The one on the left is a brick, so what does that make the one on the right? They really seem to be made of different materials. The one on the right measures approx. 16.97 mm and the one on the right approx. 22.46 mm. The one on the right has parts that glow under the blacklight and I'm not sure about the one on the left yet, I haven't had a chance to get out the blacklight to look at it yet. Any thoughts on what the one on the right might be? Thanks again for any help.
