I also have a Maximilian Lang violin. I purchased it in Calgary in 1969 and have played it ( and loved it) since. Upon purchasing it I affectionately named it Max. Max has a beautiful rich tone which others have commented on, but he also has no number on the label and I am curious why. Over the years Max and I have performed with various groups through England, Scotland, Budapest, Prague, Vienna, and just last year in Florence and Rome.
