Hamilton Standard prop id help

[Urbanhab409]

I found a prop that I need help identifying. HSP 26. MFG 513761

Tc464b31TD

By the shape it looks like it could be a 6477 blade or the longer 6501.
Do you have the length of the blade?
The 6477 is about 63 inches long/tall.
The 6501 is about 75 inches long/tall.
The "HS 26" is the alloy that is being used.
The "MFG" is the serial number for the blade.

Drawing 65718-0

That drawing # is for the shank of the blade.
You need to look for the 6501A-0, 6507A-0, 6519A-0, OR 6547A-0 marked on the blade butt. The "-0" is the diameter reduction from nominal as these are 13 foot diameter propellers, so the blade is half that less about 3 inches for the center of the hub where it mounts. You said in the other post that it is 66 1/2" tall so it could a shortened blade.

6571a-0

6571a-0

The 6571A-0 blade was used in one place as the light weight DC-3 propeller in a 33D50 propeller. See FAA TC Data sheet A-669 for the propeller and blade, and the Propeller is under P-851. It could have other uses on military aircraft.
