Hello
@setible and
@Syrte, I consulted Patrick Linder's book "At the Heart of an Industrial Vocation" and these were the relevant heights:
12.68Z = 4.25 mm
27.0 = 4.25 mm
12.68N = 5.45 mm
27M = 3.20 mm/4.30 mm (center seconds)
I suspect that the Ranfft dimension of 4.6 mm is incorrect, as Linder's book shows an image of a caliber 27.0 parts list that states a height of 4.25 mm.
