I believe, with regard to color pattern of the Spangled Orloff, the genes responsible are more like what we see in the mille fleur color pattern with the addition of the Mh (mahogany) gene. The Mh acts as a columbian like restricter of black. This would also involve the mo (mottled) gene and the Co (Columbian) gene to achieve the desired pattern of red/black/white. True spangled breeds involve both the Pg (pattern) gene and Ml (melanizer) but would lack the Co and mo genes. For this reason, I believe, the term spangled is a bit misleading in reference to the Orloff. I am not suggesting it be changed, simply stating that it is a bit of a nomenclature issue when trying to pin down the genes.
