Tumi voyager Carson backpack - gold hardware

I bought this bag in 2022 for trips to the office and I just don’t go that often. Also not a fan of gold hardware as of late; I would be up to trade for the same bag with the gunmetal hardware as I can not find it anywhere. This bag is in excellent used condition, no rips or stains. The outside nylon is not scuffed. The zippers all work and the leather zipper pulls are intact. The bag is not registered, I wasn’t aware of what a big deal it was at the time, unfortunately I don’t have the knowledge if you can register a used bag with Tumi.
