Hi. I recently acquired a propeller from a woman in her sixties that said it belonged to her father who was an airforce pilot and later flew for the Bethlehem Steel Corp in Allentown PA. I can find no markings on it. It is not cracked and appears to be oak and in good shape. I cleaned off years of dirt. The small holes you may see were from small straps that were used to hang it on the wall. Interested in any info and approx value. 100 inches long and 10 inches wide at widest point. Thanks.
