Cindylu- I am interested in your question because I was the Cheif Woodwind Technician and Designer for the SELMER Co and did the designing of the BUNDY II saxes. A bit of history---- for many years previous, the BUNDY saxes had been made by the BUESCHER Company in Elkhart, Indiana, the home also for H. and A. SELMER, at 1119 N. Main St. The body design was the same as the famous BUESCHER TRUTONE saxes, which were pattented in 1914, and were so fine that Sgurd Rascher, the world's finest player always used one. There certainly was no way of improving on that, so my attention was focusewd on variations in the mecxhanism, especially on the reshaping and location of the table keys for the left hand little finger. There were a few other minor changes made, but they were not what contributed to the sudden spurt in sales we enjoyed. The regular BUNDY had been by far the most purchased student model for years, but the first year of the BUNDY II saw a 38% further increase in sales. I see many blogs from supposed "authorities" for saxophones, especially SELMER models, but see very in the way of really accurate knowledge, such as I have after 30 years with the company. I retired 26 years ago, so witnessed the growth of the company at first hand. I wish you all the best in the musical world, Musically yours in Christ, Ralph Morgan
