Thanks very much Bo! I want to apologize right up front for going ahead and making the propeller before you posted this information. I should've waited for this material or sent you a PM, but all of a sudden, there I was, shaping a piece of brass. As luck would have it, I'm right in the ballpark with the measurements you've provided. It might not look as good as the kit supplied piece, but if WnW do send along a replacement, it'll do until then.
Thanks again Bo for going to all of this effort on my behalf. I hope I can return the favour in the not too distant future.
Cheers,
Chris
