Schott Perfecto ID
I recently bought this jacket without knowing much about Schott jackets and I'm very curious to have it dated. I'm pretty certain it's a 618 given the label, but I've got no idea of when it was made and whether or not the new faux fur collars you sell fit this particular jacket. If possible, knowing what kind of leather it is would be fantastic!
The leather is thick and stiff; I'd very much appreciate some help on ID:ing this jacket!
Best regards and thank you for helping out,
