Thank you; for me, being trained in the Maurice André way of playing #4 valve with the left index finger, this horn is not suitable, lacking the mechanism to operate # 4 this way. It was difficult enough with my Scherzer G (lovely horn, loved playing it until I inherited a Selmer G from Maurice André)...
