I haven't been to the Smithsonian since 1964; at that time, if I remember correctly, the once coal-black Reinzi had faded to a disgusting pale YELLOW from having stood where he was daily in direct sunlight pouring in through a window or door. When did you see him, and what color was he? IF still on display, I sincerely hope the hide has been "conserved", including being dyed back to its original color; but since Civil War history and patriotism are passe in modern Washington, and SURELY there's nobody around who ever heard of Philip Henry Sheridan - much less his HORSE - I suppose it's been consigned to the same storage bin as the Lost Ark!
