The one on the right is quite indistinct, and the second picture is even worse.

I agree 100%, however finding the BNC female connector with the base mount is proving difficult.

The knob in the second picture has a kurled tip and either pushes in (like a button) and/or twists like a volume adjustment. Maybe a potentiometer?
