This Trio Sonata was previously thought to have been by Graun. The title page suggests that only the figures in the Bass part were added by Graun.
According to Tobias Schwinger (in 'Die Musikaliensammlung Thulemeier und die Berliner Musiküberlieferung in der zweiten Hälfte des 18. Jahrhunderts', Ortus, 2006), the original instrumentation is oboe, violin and continuo. The title page, along with the addition remark 'o Flauto' on the oboe part, was added later by the copyist 'Anon. Itzig 12' (identified as F. Baumann).
Although F# minor is an extremely strange key for oboe, it is likely that this Sonata was written for the Berlin Oboist Johann Christian Jacobi (1719-1784). Marpurg, in "Historisch-Kritische Beyträge zur Aufnahme der Musik" describes him as a "worthy oboist" and also says that Janitsch composed Trios, Quadros and Concerti in the usual and unusual keys. A note dedicating a Trio Sonata in D-flat major (!) to Jacobi can be seen here. There are also other Trios by Janitsch for oboe in A major, A-flat major, E-flat minor (lost), B-flat minor as well as several other in more "usual" keys.
