Just another quick observation to share: I have had about 6 of those "Lacy" style Links through here, including Steve's and the one I play.
Each of them had that "racetrack oval throat" but every one of them was a bit different in shape- some were rounder, some were narrower, some were more square (but not nearly square in reality). And each had a slight but real difference in the way it played.
BTW, the workmanship on Steve's piece, done at the Link factory, was beautiful in every respect. There was obviously a lot of time and care given to making Steve's pieces. I only saw the last of his Links, which makes me wonder about the others, if he chose to play the others over that last one. And the last one is a gem!
What were the others like?
