So there has been a lot of questions regarding what exactly makes the leather different from the '05 paddingtons to the '06 paddingtons. The difference is hard to show in photos because, to me, it's more the feel of the leather. But I will try to show you photos of both leathers so you get a general idea! It has been said that the '05 paddingtons have the softest and vintag-ey leather. The '06 have been claimed to be more stiff and "upright". Whatever your preference, there is a difference! I hope this helps! Reference: Chocolate is '05, Whiskey is '06 Pic 1: Side-by-side "sitting" stance. Notice that the chocolate slumps more. I equally stuffed them. Pic 2: Side-by-side stance. Unstuffed. Pic 3&4: Close up leather. Notice that the pebbling on my whiskey is more even. My '05 chocolate actually has no pebbling, just textured leather. Some '05 did have pebbling. Pic 5&6: Close up leather. The chocolate '05 color is not uniform. It is darker in some spots than others. The '06 color is pretty uniform. Notice how the chocolate '05 leather looks softer and thinner. The whiskey '06 is made of thicker/tougher leather. Set 7&8: Interior Canvas. I tried to take a photo of the interior lining. I am not sure if it is showing through, but you can tell that the whiskey '06 lining has less wrinkles than the chocolate '05. That's cus it is much thicker. Set 9&10: Padlocks. The '05 chocolate padlock stitching is straight. The '06 whiskey padlock stitching is at a slight angle. The color metallics are different too. The '06 padlock is made of 50% brass and 50% zamac. The '06 padlock is slightly smaller and lighter than the '05. Points 10&11: I don't have a photo of this, but my '05 chocolate has a 6 digit date stamp on the left side of the interior pocket while my '06 whiskey has a long serial number on the right side. Is anyone else has leather comparision photos please post them!
