Both of these parts came with my G&P crenellated bezel that I now have on my 9P. The silver piece is a non-threaded aluminum ring. The black one is a threaded piece similar to the original 9P lens retaining ring.
Of course, there were no instructions with the bezel. What are these for? I'm not using either piece and my 9P seems to be just fine. How can these be utilized?
