Part III is undoubtedly copied in a single hand (Conradus de Dyffenbach) and not in two hands, as stated by E. Poulle, Les instruments de la théorie des planètes selon Ptolémée: équatoires et horlogerie planétaire du XIIIe au XVIe siècle, Paris, 1980, 93, who sees a new hand starting on f. 46r and dates f. 46-68 to c. 1460-1480 due to the positions of the apogees in the equatorium f. 59-62.
