I saw these, and this is one reason for asking actually - those look almost "chocolate" in color, so I assumed you had some double secret squirrel models that nobody can actually buy... :^)
But most photos I can find on line seem so portray plain "snuff" as more of a caramel color - are yours "snuff" or are yours the "Dark Brown" version like the ones from TSM?:
Mine are labeled as snuff. I bought them from O'Connells during their Alden clear out sale. I can pull the model number out of them when I get home. Snuff varies a bit from shoe to shoe, batch to batch kind of like Shell.
I agree that snuff can vary. But even in its darkest form it comes nowhere near Alden's mocha (dark brown) kid suede. I have various models in each color.
