D-B, Mus.ms. 20375 (olim: 33)
D-WÜd, KBD/KES K7 Ms091; this manuscript originates from the Cistercian monastery in Bildhausen.29
In all the known sources, except for the inauthentic arrangement in D-KA, Mus. Hs. 230 (used as a basis for the present edition) the upper part is written for violin.
In the manuscript from D-KA, Mus. Hs. 225 (used as a basis for the present edition) this work is transposed to G major and incorrectly attributed to Ivanschiz. In all the other known sources the trio is written in F major and scored for two violins and basso (i.e. cello or violone). In all probability, it was composed by Franz Asplmayr. With this attribution it is preserved, inter alia, in CZ-Pnm, XXII A 147 and in S-Skma, C 2-R. Neither of these sources was known to Pokorn. In addition, this composition is mistakenly attributed to Joseph Haydn (Hob. V: F3) in A-SEI, N II C 64.
In the manuscript from D-KA, Mus. Hs. 229 this work is transposed to D major and incorrectly attributed to Ivanschiz. In all the other known sources the trio is written in B flat major and scored for two violins and basso (i.e. cello or violone). It was indisputably composed by Franz Asplmayr. With this attribution it is preserved, inter alia in CZ-Pnm, XXII A 146 and in D-ZL, no shelfmark. Neither of these sources was known to Pokorn.

29. Interestingly, this is the only known manuscript of Ivanschiz’s trios that suggests the presence of a basso continuo realization. Its title page contains the following inscription: “Sonatina Tono Del C | â 3 Stromenti | Violino Solo | Viola Solo | Con | Basso Continuo”. However, the simple label “Basso” heads the lowest part, which is not figured.
