Uh... Fw 190 V15, 16, 17, 18...or FW190 V32? It's got to be one of the prototypes that Fw fooled around with. Impossible to tell exactly without more info I should think.
If that's the case, isn't the leading edge of the spinner kind if hard? They were open ended without cones but they had rounded lips on them.
Lets see some more!
