Additional Comments
1/20/2025 Update: I've elimintated the internal air hiss for the GP9 bell, as it is hand-rung, not air-powered.
9/1/2025 Update: I renamed the interior bronze bell sound included in the P3 folder, as there was no interior bell audio. Also added the missing interior hand-rung bell to the RS3K folder.
