Can you identify this PA-28 autopilot/ Audio Panel?

Hi,
This is more for my curiosity, I had block time a couple of years ago in a '68 Pa28-180 for a trip to OSH. It had an old autopilot/ wing leveller(?) for which I couldn't get to work nor find any manuals in plane or online to tell me what it was and how to operate it. Plane is no longer owned by same guys, so can't ask.
Here are a couple of pics, Can anyone identify for me ?
Like I said its more curiosity than anything
