I have three of Fred Cox widow maker ltd edition wing bones. Fred made these at the start of each year and all mine are number 7. The three bone is 2012 and the two bones are 2013 and 2015. All are new and only played a few times. They also have the center slide like Parker Weeden used on his calls. Asking 75 each TYD payapl, check or mo. https://imgur.com/a/Alk3N https://imgur.com/a/ExNvc
I should have been more specific, do any of the Fred Cox sliding wing bones have hen bone mouthpieces?
I would say yes on the three bone and the 2013 two bone.
