Up close of depth coil suspension

This is where record cutters raise questions about cutting, and trade wisdom and experiment results. We love Scully, Neumann, Presto, & Rek-O-Kut lathes and Wilcox-Gay Recordios (among others). We are excited by the various modern pro and semi-pro systems, too, in production and development. We use strange, extinct disc-based dictation machines. And other stuff, too.

Can anybody get, or possibly have an upclose view of a depth coil suspension? Or possibly exploded schematics of one?

I recently had to clean and lube the bearings and took this picture of the bottom of the Neumann suspension box.

The coil is on the left. It's basically a speaker motor with a shaft connected. The shaft attaches to the bottom of the head mount on the right. The head mounts on the right side of this box. Bearings allow for rotation of the head mount. When the coil moves the head rotates causing the the tip of the stylus to move up or down. Very simple. Very clever.

Do you have any shots of the head lift mechanism by chance?
