"Beginning in the late 1780s, we start to see a new and different style from the Storioni workshop, a style which by 1790 is dominant and which is seen with but few exceptions for the rest of the maker's career. These characteristics are apparent in the violin of 1792 -- the rounder, more Amati-like outline, the fuller arching with greater scoop, the rounder, shorter, almost pinched looking F, and the scroll, with longer pegbox, smaller and weaker volutes, and without the typical extra turn. It is interesting to note that the period during which we see this model substantially conforms with the apprenticeship of Giovanni Rota."
