I would reach out to their service department. Pretty sure you’ll be able to get them straight from Lacanche.

Hello,

First, congratulations on your Chagny !

As suggested, if you can't find someone to swap, you can certainly order the Brass trim pieces directly from us (or Art Culinaire if you are in the US).

The knobs are easy to swap of course, replacing the handles supports is a bit more work but nothing a moderately-skilled (and careful!) handyman couldn't do. If you ever need assistance with this, please feel free to reach out at support@french-barn.com
