This is Bach's own transcription.
Sure, I did not mean to imply otherwise.
As I said, I am usually for original versions anyway and prefer the keyboard versions of the trios. Nevertheless I acquired the following discs I mention for those interested without evaluation
Camerata Köln on cpo with the gamba sonatas "beefed up" by violin in the g minor (this close to the Buxtehude combo), recorder in the D major and flute in the G major. Plus the organ sonatas 525 for flute, violin, bc and 527 for recorder, violon, bc.
Hantai & amis with 525, 529+530 for recorder, violin, bc. (only in the naive Hantai box, otherwise oop).
Freiburger Barocksolisten (still modern instruments, rec. 1984, not sure if any overlap with the later Freiburg HIP ensembles) on Christophorus CHE 0053-2) with reconstructions of a C major (BWV 1027 + 1039), flute, viola, bc, one in b minor (BWV 178,104,92, 36) for 2 oboe d'amore, bc, on a minor (BWV 1030/B) for oboe and cembalo obbligato and a g minor (BWV 76 and 528) for Oboe, Viola bc
