Schott 618. Worn only twice. In my opinion, considering the number of times worn, the leather is in beautiful condition, but it's not deadstock. Please check the images for the condition. There is some discoloration on the metal at the back of the collar, but it has been cleaned by a leather specialist and stored without being worn since. One owner, but it's still used. As it is vintage, please refrain from purchasing if you are looking for perfection or are overly sensitive. Thank you. It is a vintage item, and it has been stored by a non-professional, so I have marked it as having some scratches and dirt.
