Propeller I.D. Needed

[Rikkn]

I need help identifying this propeller blade. It is 13 in wide, 58 overall length. I had once thought it was an Allison division produced part, but can no longer verify that. My thoughts lean toward medium size bomber. Would love some help here guys.

A pic of the general view of the blade would be useful too.

This is a hollow steel Aeroproducts blade, drawing H20H-162-40M5, used in the A422-E1/E2 propellers that pulled the NAA T-28A with the 800 HP Wright R-1300. Installed diameter is 10 foot 0.5 inch. P-51 air racers and Tsunami, loved these high-activity factor blades The prop manual and revision update is attached.
