Catalogue Illustration of a
Hupfeld Model B
Phonoliszt-Violina

This typical catalogue illustration is from a circa 1912-1914 Hupfeld catalogue, The Model B Phonoliszt-Violina was a very popular case style, exemplified by the fact the most surviving examples are of this style. However, one disadvantage of the sleek Model B design is that there is no room to accommodate such options such as the cumbersome duplex roll changer, which possibly explains why the two surviving duplex models, (one early and one late) used the Model A case.
