So I've been using my Pentax Super Takumar 50/1.4 and I've loved it since I got it. Recently I've discovered that the decoration ring (image below) has loosened and is breaking away from the lens. Optically the lens is still good but the ring is only held in one place, rather than three. One screw also came loose (it keeps the front element to the body or so it looks like) but the rest of the screws are still good.
What's the safest way to attach the decoration ring back to the camera lens?
You can see that I can fit post-its and other stuff in the gap...
