Burrus Plug-in Armed Sconce by Mercury Row in Brass

This is the Burrus Plug-in Armed Sconce by Mercury Row in Brass. I bought it from Wayfair and only used it for a few months before I moved. 🙃 The lamp has a few scratches on the body, the majority of which are on the back of the neck (the part that faces upwards to the ceiling). The lamp also hangs slightly wonky (it arrived like that from Wayfair). I've included a few photos of this and how it looks when hanging. Please let me know if you have any questions!

I have one million random screws in a box and I cannot for the life of me figure out which ones belong to this thing. I'm sorry! Please let me know if you have any questions at all!
