Getting interesting relievchair. Thanks for your input.I'll take a swing at it as being a hook patterned after China's Shang Dynasty.
Mouth is unique , in a way.
One of the first I copied style of drawing years ago.
No authority. I won't swear this is Shang , but note the mouth/face vs other dynasties. You might find something closer than my lazy butt!
Fish. Fish! Koi depiction? Carp?Do a google search. Type in vintage fish ceiling hook.
Very similar on a popular auction site
It looks close but this one is heavier than cast iron. I think it is brass or a brass alloy.
