Appears in a list of Breitkopf publications in the Intelligenzblatt, AMZ, March 1802. One guesses this is not the first edition and that it first came out earlier, but it does establish that it was first published no later than 1802 (perhaps a good deal earlier, but better to have a firm upper bound than something fuzzy.)
Another "Grand Trio" by Dumonchau, dedicated to Auguste de Sayve, was published in 1807 or 1808 by Auguste Leduc (predecessor of Alphonse Leduc?). (see Journal typographique et bibliographique..., Volume 11 (nos. 12 and 13, March 21&28, 1808 issues, p.93.)
