Hello hello,
it seems like the models for Honor/Willful/Glory weapon skins for reaper have vanished from the game. Tried unchecking and checking the skin itself, nothing changes, the model of the weapon remains the same default one (Entropy, in my case). Trying to look for these skins on auction and preview them on your character model also doesn’t work, the preview just shows your actual weapon.
