Help with prop blade ID

[turbo]

Hello
I'm Trying to find out when the prop blade shown in the attached pictures, would have been made and the possible aircraft it could have been used on. This cut off blade measures 48" x 9.5" (at widest point)
Any help would be appreciated.

I think Bob Gardner may come along and admire the decal, and possibly provide some more info, but typically it's nearly impossible to identify aircraft usage by the shape of the blade alone.
