Leguina 1891 records this Spanish manuscript translation of Nicolás Demeuse as a substantial quarto witness with 332 pages, 13 large pen drawings, and 4 index leaves. He notes that the printed French original appeared at Liège in 1778, followed by later editions at Liège in 1786 and Lille around 1800, but keeps this manuscript translation as a distinct local witness.
Recorded by Leguina and Thimm as a manuscript. It is catalogued separately from the French printed Nouveau traité de l'art des armes of 1778.
