Quality phase 376: MS X.911 is one of three anonymous French witnesses traditionally attributed to Pedro de Heredia. The attribution originated in a later catalogue and remains disputed; French language is not treated as proof of French production.
Quality phase 391: distinguished the complementary Glasgow objects. E.1939.65.360 is the 210-page textual Book of Lessons; E.1939.65.359 is a related series of 54 watercolour plates with captions. They are not two equivalent complete copies.
