I have just discovered a rather disturbing thing while cleaning out the clarinet. it appears that on the bottom part of the top joint(ie. the bottom of the top joint just above the cork), a piece of wood supposedly has fallen off? however, it seems that beneath it, it does not appear to be wood because it appears a silvery color? what does this mean? as far as i can tell, it does not create a leak since it appears above the cork, not below it, but this is still rather disturbing. I've surmised that it is because the silver above the wood in question appears a bit rusted. It's where the two screws sit right at the edge on top of each other. anyone else happened to have discovered something like rust there? if it helps, i have a 1964 buffet, probably r13 or something, model number 79740.

1. Posts are often screwed well into the timber. Is it the 'root' (seems a good name) of the post that has the two screw in it?
2. On some clarinets, both the upper and lower posts of the C#/G# key are soldered to a single metal bar (for security of mounting) and this bar is embedded in a groove cut into the timber, secured by a couple of screws into the timber. Could the chip have exposed the end of such a metal bar.
In either of the above cases, the metal will not be steel, so it cannot rust. It is most likely to be 'nickel silver'.
3. At some time the entire tenon, or part of it, has broken off and as part of the repair, metal reinforcing rods were inserted for strength. These could be steel. If this were the case there would probably be some sort of evidence of holes having been drilled at the very end face of the tenon. If the steel rusted it would occupy more space and force off a chip of timber.
4. At some time the entire tenon has broken off and as part of the repair, a metal sleeve was installed in the bore, and this has been exposed.
5. During manufacture there was a problem, and metal was somehow inserted for reinforcing as per No. 4, or for another reason, rather than throwing the whole joint away.
6. At one time the body was split, and as part of the repair, a metal rod (probably threaded) was inserted inside the timber wall, at right angles to the split.
That's all I can think of at present.
