Autohelm 1000 wind vane

[907Juice]

Hello all, I have a old boat with likely an equally old autopilot. Bought the boat used a few years ago and just learned there is an accessory that would be nice to have. No biggy either way just thought I'd ask. Thanks for any help if anyone knows where to find it. I've searched cl and eBay with no luck. I'll be back on the boat mo day or Tuesday and can post a pic if I don't get a response.

Thanks!!
