In the '70s I used to tune the thing in his house. It was only special because Franz Mohr regulated the (german) action beyond recognition even though at that time Horriblewitz wasn't concertizing. We kept three for him - one at his house, one in a special cold room in the Concert Basement, and another one I forget where. He was a wonderful old fart and I only did it twice. The first time I was anxious to get to my next job but he played a bunch of Chopin etudes. It was pretty good. Ben Treuhaft Havapiano (Senda Piana to Havana)
