I meant Recessive blue Smokey. I doubt it's been imported to north america, but it's always possible to have a spontaneous mutation (remember, the Buttercup genotype mutated 4 times in Leghorns, Dutch, and OEGBs)
Huh?

Smokey is a revertant of dominant white. It is dominant to dom.white (I), able to reverse some of its effects. You could interpret that as that it works towards the same goal as the wildtype gene i+. Maybe that's why it is recessive to it. Dominance to dun is unknown.
