One of two scanned copies of this work found using the REX catalogue at DKB.
mu 6210.1528 from Copenhagen. Described as "?sonata?" at RISM. Staatsbibliothek zu Berlin has another copy of this work (RISM files under sonata but their note of the heading still says solo; the latter is in a collection of copies of "6 Sonatas" however by various composers, in a late 18th-century copy.)
