What tells a Wing Leveler its position?
If it's an old Century 1 autopilot (wing leveler) it's a turn coordinator. What kind are you referring to?

Need help? Let me know!
My old unit in my 1970 Cessna utilized VOR for position info. Not much help!
In the case of the Tru Trak Vizion, it has an internal sensor that tells it when it's level.
I love to defy gravity!
1979 Arrow IV
I have a Vision install scheduled for June 3. Anticipating the date already!
Mine is like Scott described. A Century 1
On my 76 Arrow it is the ADI. (Piper Altimatic 111B)
I have a 1966 PA-28-235. There are no significant marking on the unit face to tell me which one it is. Help !
Hi, we really need to know what you have in your panel. Can you take a few photos and post them? That will get us a few steps closer
Wing Leveler for 235
Somewhere in your maint. records including a FAA form 337. This should be documented. Hopefully you can get some info from that. I've never seen a unit that looks like that.
Hi Austin and Cobbler: I've been around the block with autopilots on Pipers since about 1964 and I've never seen one of these. It doesn't seem to be Century, Britain, Sperry or King. Who else was out there in 1966 or later?
Can you pull the unit out? there should be a data plate on it somewhere.
Here's a comment from our avionics guru, Bob Hart:
I believe that is the original “Autoflite”, the first autopilot I mention in my legacy autopilot article.
Photos are hard to find and I may not have included a photo in the article.
That, in it’s original version was in fact, a wing leveler. You could add tracking to it.
Tell the guy to run. There’s nothing there worth doing anything with.
Thanks for your comments
