New project

I bought this kind of wheel in an antique store, i found it very pretty. I have no clue what it was.
I was thinking to hang it on the wall above my sofa.
It´s made of steel and has a old gold /brass colour.
I took the picture with my iphone in my warehouse with poor lighting, sorry for the bad quality of the picture. You can see my foot in the picture to give you an idea about it´s size.

What shall I do with it. Paint it yes or no, and if so wich colour would you paint it? I need your advise...
