grey miyata saddles

Does anybody know if the grey Miyata saddles at mys-co (Japan) are different from the green/red/blue ones? There’s even one that comes with rails for a regular seatpost:

last time i had any info on those was from jolly ol’ Sendhair (he lives in Japan) i had him look at the bottom for any sing of the word “JAPAN” on it and he said there was’nt so i would venture a guess that they are made in China too.

he also said that the where $35 dollars and included the rail adapter.nice eh?
