I googled.Are you thinking of Golden Comets? I've never heard of Golden Buffs.
Some hatcheries or resellers (including My Pet Chicken and Purely Poultry) list "Golden Buffs" that look just like red sexlinks (aka Golden Comets and Red Stars and ISA Browns and.... ). The description for the Golden Buffs talks about how the females and males look different, too, which made it very clear to me that they are just red sexlinks under yet another name.
