This is the fine ("micro") focus on the front standard of a Toyo 810G. Below is a picture of it.
There's a small hex screw that you can make out just past the knob. The smallest hex on my bicycle tool fit into it but it wouldn't turn. To the right of that is the lever for tightening the focus lock. The focus remains stiff but I'm sure that it's supposed to tighten firmly when the lever is fully engaged. Any experience with this part?
Thanks,
Thomas
