Leather steering wheel 420mm

I have a 420mm steering wheel in leather and i wonder from what 911 this is? Or is it from a other Porsche?
Does anyone know this?
Thanks.

67-68 911s, l

Thank you for answer the tread!
But are you sure about that? The book from Brett Johnson says that all the wheels are 400mm...
I need a steering wheel for a 66-67S. Is that a 400mm wheel?

Thanks!
