I don’t remember who it was on my dash that was looking for Yuxi’s recolours of Birgit’s classic silver mirror shared @ TBTO, but here’s a belated response: I happened to stumble upon Yuxi’s Onedrive and apparently they reuploaded the set, you can find it in this folder (the file is yuxi-obj-B43classicsilvermirrorretexture).

Pic for reference, in case anyone else might want the set.
