WWI wood propeller

[drich1939]

I have a wood propeller that measures 8' tip to tip. it is dark wood possibly Walnut with copper(?) shielding on the leading edges. There are eight bolts and the only markings i can find are a series of numbers and letters which are as follows: SC9599. I haven't done any other measurements yet. I called Hartzel engines person I talked to said maybe an OX5 and a Post WWI engine. I know nothing about researching and like some guidance on how to find more about the propeller and possibly a value although I am not really wanting to sell it.
I am not at all familiar with all of the things I need to know on this site such as sending pictures etc.

I just downloaded three pictures of my propeller. I don't know how sinc them to my post????????

There is really no substitute for a series of photographs showing every detail but, as a starting point, I would suggest that you could narrow down the possibilities by referring to this page, accurately measuring the relevant dimensions and comparing them to the hub dimensions chart.

I somewhat jokingly equate these questions with, "I found a tire that is two feet in diameter, and I'm looking for information and value". Most of us realize that there are hundreds and maybe thousands of possibilities with tires, but there may be a similar number with respect to propellers. And like tires, propellers were very frequently replaced due to damage or even just aging and wear, so they were produced in large numbers.

Unfortunately, the database available to identify propellers, especially WW1 propellers, is very limited and even in the best of circumstances may involve significant guesswork.


All we know about your prop is that it was manufactured for the U.S. Signal Corps, but the number associated with that stamp does not provide any specific information. Photos are essential. Also see this page with respect to valuation.
