Not looking to know the diameter -- just the length of a single blade. It's for a recovery project in the SW Pacific.

Have you tried the Pima Air Museum, USAF museum in Dayton, or Udvar Hazy (Smithson in D.C.) Would think they could give you the exact specs.

I did some digging around, and I wasn't able to come up with the length of the blades by themselves. However, I do have the Hamilton Standard model numbers (from the B-24D erection and maintenance manual) for the blades used on the B-24D- all planes prior to s/n 41-23970, plus s/n 42-63751 to 42-63757, were factory fitted with narrow 6153A-18 or 6353A-18 blades, while all other D models came out with wide 6477A-0 blades. Perhaps contact Hamilton Standard, which is now part of United Technologies, and see if they have the info available:http://utcaerospacesystems.com/Pages/Default.aspx

...of a B-24D kit prop and multiply by the appropriate scale. If you have a scale ruler, use that instead of multiplying. Suspect that would be close enough to the block number referenced.
