WSOR 101's Nathan M3 diagnosis

I'm pretty sure I know what's wrong with this M3. Probably the #4 bell's parts are either rusty, gummed up with oil, or just worn out. The other two bells are gruff but they're playing the correct chords. As you can probably see, the #4 bell's dirtier than the others. Or there could be blockage in the manifold. I'm just clarifying.

Sounds like it's blowing, just really weak. Could be a cracked diaphragm or worn diaphragm seat. You'll have to disassemble it to figure out for certain.

Open up the back and see what's going on (or not going on) in there.
