Alden 35mm Color 8 Shell Cordovan Belt w. Nickel Buckle - Not being produced right now.
Pretty sure that US retailers aren't allowed to put their Cigar, Whiskey, Ravello inventory on their websites by orders of Alden. (It was explained to me by one retailer that this is to protect their international retailers from being undercut.)
So you won't see any of those colors listed on retailers' websites, and even if you did, it would probably be too late by the time you saw it. As others have alluded, best bet is to call, or even better visit in person if possible.
