What Pan American said in 1938:
Popular with professional and school musicians because of the same fine qualities as the bell-front, side valve
action model. This model features the upright bell and the top valve action preferred by many musicians. Built
in Bb with same bore as bell-front model, correctly designed throughout, light in weight, sturdily built and beautifully
finished. 27½" high; 11" bell.
