I feel like statues are, to some degree, who we say they are. Like if it has Nephthys’s or Isis’s hat on, that’s one thing, that clearly says who it is. But otherwise? It’s mostly up to us. My statue (from the same series as yours) is I think technically a reproduction of a statue of Wadjet, but most people I know “recognise” it as being Sekhmet-Mut, or at least Sekhmet. Which is valid! I used it as Sekhmet-Mut for a while as well and got no complaints. I also use an “Isis” statue as Hathor, because I was told to. There’s no hieroglpyhs on it saying different, so, no issue
I love when statues are obviously choosing to come to us. It feels really nice.
