That's a beautiful prop Frank. I did one for the 1:32 Roden D.III several years ago and failed on the first try however I was able to succeed by doing two 2 blade props and then joining them, I think not as efficient as your method with four blades from the beginning of the construction. The grain and veneer on this one look great!
Being in the larger scale I was able to use 8 layers of veneer, it took a lot more time then the standard props I usually produce.
As always your work is exceptional, and I'll look forward to following your progress on this beauty, one of my three top favorite WW.I aircraft.
Cheers,
Lance
