I have a Sensenich Brothers wooden propeller in great shape. In looking at this site I have the same propeller as Zephyrus23, mine is in far better shape. The edges are all intack, the decals are complete and the black paint is also intack. This propellers was used on a PT-19, manufactured between 1932-1942. The military design number is 42K15729. My father-in-law was stationed in Camden Ak in 42 and worked on these. I have pictures of him with three of these in the shot. I have seen this propeller on a bi-wing plane in the Henry Ford Museum in Detroit I am interested in selling this item.
