Used worm gear that looks good, other than slight scuffing on the bearing contact surfaces. Bought a new worm for $50 right after I paid for a used G-11 here from an Astromart'er, thinking it was in need of a high-precision one - turns out it already had one, so I just replaced it. This worm gear is the one I pulled off the G-11. $25 shipped CONUS, PayPal preferred. Thanks for looking!
