P1000416 (2) prop.jpg I recently purchased this prop at a local antique shop. It is 8' 4" with copper on the leading edge and tips with copper nails. I believe this style is refered to as "tooth pick". There are 3 sets of numbers stamped in the hub along with the dia. Inboard of the dia stamp is the no. 585. The center is stamped 986 and across from the diameter stamp is the no.42206 . I am interested in who manufactured it and where and an approx. date of manufacture.
