AMI "C" cam Help/Pictures needed

[AMI C]

I am having some problems figuring out how the phonograph needle is moved to the record, and then lifted back away.

I am looking for some close up pictures or videos of the cam and associated parts from the rear of the machine forward, especially how the gears mesh when the gripper arm is over the record rack, and over the turntable.

If anyone has any pictures or videos they can share with me, it would be greatly appreciated.
