Prop id help needed

[Tcthielen]

Unknown prop. No decal. 98 inches, 8 bolt, number 475 penciled in to hub. 4 inch Yellow tips with 11 inch olive section. Prop is about 6 inches thick at hub and center is 3 3/4 bevelled to 4 1/4. New to forum if you would like to help sure appreciate it.
Thanks

It could be almost anything, as many propellers look identical but were used on completely different aircraft. There should be stamped numbers on it (either on the blade or on the hub) which would help identify it.
