I am also asking about the possible authenticity of a component, in my case the metal clips that attach the strap to a NYC Basic Bag, Whateve kindly authenticated for me yesterday.
The clips should be brass, but they are not. Some type of metal that it's peeling and looks bad. The possibility of the strap belonging to another bag was brought up as well. To me the color and condition (same patina), match both the bag and strap, so just hoping that for some miracle these clips (they say Japan), were made at the time and used by mistake..? (I know.. hoping for too much).
I took one of the leather covered clamps thinking I would find the strap in two pieces so that's the way to change the clips, but it looked like only one piece (perhaps glued), very old and professionally done, nothing that looked like "fixed" at one point.
I will welcome any input and thank you for your time.
