I bought a '06 Paddington Medium Satchel. The serial number is 01-06-53. I know the middle is the year, but what do those other numbers mean? Also, the color is like a dark green, khaki, grey color. I will try to post pics, but anyone know of this color and the name of it made in '06? It is also missing the key and the string that attaches to the bag. Does Chloe sell replacement keys? Thanks all!
