You might be describing special order or LE items, but if it is a mass produced bag like a regular Speedy the hardware should be identical no mater where it is made.
I got a cles less than a year ago and even though it is MIF, and the zipper pull is peeling, so it is a coated metal, not a brass.
This is correct. For all lower end (mass-produced factory models), they are coated metal - no matter where they are made. That would be virtually everything under $3,500 to $4,000.
