1815 · Paris
With different titles to Violino Secondo and Basso parts ("Six Trios Pour Deux Violons et Basse ou pour Violon seul et Piano Dédiés à sa Mère... Divisés en deux Livres. Œuvre 1er Livre  Prix 9f.") and different publisher's addresses ("Boulevard Montmartre No. 31, presqu'au coin du Faubourg Montmartre" to Violino Primo; "Boulevart [!Boulevard] Poissonière", No. 20" to Violino Secondo and Basso).
Edges slightly browned; impression occasionally light; final page of Basso part printed upside down. First Edition, mixed issues, with the Violino Primo part being one issue and the Violino Secondo and Basso parts another.
Dating the Violino Primo issue is difficult because of contradictory criteria. The Violino Primo part has the title page of the first issue (1800), containing the publisher's earlier address (valid through 1805; see Devriès-Lesure I, p. 120) and making no reference to the arrangement with piano accompaniment; the correction to the final line of the title, where the original reading "Enreg[istr]é à la Bibliothèqu]e Nationale" has been changed to "... Royale," however, points to a date after 1815 as do the added metronome markings. The plate number "13" is also a later addition; although "Livre 1," containing the first three trios of the collection, had the plate number "12" from the beginning, the first issue of "Livre 2" had only "b" (see digitized copies of the first issue at the University of Western Ontario and Eastman School of Music, both at IMSLP).
The other two parts carry the publisher's address of 1807-24 and lack the metronome markings; it is likely that they were published before the Violino Primo part. (Inventory #: 25651)
