Récit de Cornet ou de Tierces au Positif

I neglected to show off the "cornet décomposé" of the small P. Ott organ with the French literature I uploaded earlier last week. I'm uploading this to remedy my oversight.

I found this piece in Guillame Lasceux's "Mass for Organ in E minor."

Here is his Wikipedia link: https://en.wikipedia.org/wiki/Guillaume_Lasceux
