1902—Boston, Massachussetts
An extensive exhibition of musical instruments hosted by Chickering & Sons at Horticulture Hall, Boston, includes at least 3 alto trombones, all pitched in E-flat. One is a slide instrument made by D.C. Hall & Co., Boston (Chickering 36). The other two are rotary valve instruments, one described as “German silver,” the other “Italian” (Chickering 40).*
