This study raises up also the need of breeding in cock breeder strain and pullet breeder strains to improve phenotype and (probably) performance.

The Schilling birds, dated to 1915, show a kind of "concentric barring".

On the other hand, any who have had the pleasure of seeing good specimens can appreciate the erratic pattern of the Dominique’s barring. One particular trait that is lost in many of the modern strains is the "eye" that is to be seen at the end of each feather. The shape of the bars and the rounded end of the feather causes this. One could almost call the final bar – "lacing". If you are unsure of this pattern, look closely at A.O. Schilling’s artwork in the black and white Standard of Perfection.

How can the described "eye" be understood genetically?
As mooney, like in Pheasant Fowl or Redcaps?

See Fig. 2 & 8
This leads me again to the question, are they based on the Hamburg family (Hamburgs, OEPF or Redcaps)?
Mooney and rose combed ancestors seems to be obviously.

I found an explanation for the "lost eye".
It can be explained by the selection for slow feathering in show strains to get a sharper barring, see also Martin (1929)
