I have this BRAND NEW Space Invaders/Qix and Ms.Pacman/Galaga 4-way microswitch joystick to sell.
The difference between the two is that the Space Invaders/Qix shaft is a little longer than the Ms.Pac/Galaga ones about 1" longer. I think its a good candidate for you Wood Control Panels.
Here is some pic of the joystick
