Just noticed the front sight bead on the double is missing its "filling" ie it is now just a hollow tube. May have had some silver solder or something in it earlier, but if it did it has shot lose already. Also shot off the front cap on the forend in the first round of testing. Came off in my hand. But can easily be screwed back in.

The front bead. What is the best color - white/ivory? Gold would be easy to do.
