This is the only Sensenich 98AA-64 propeller for sale on the on the internet. These pieces of American craftsmanship were made exclusively for the Boeing PT 13 and PT 17 aircraft. These propellers were produced from 1936 to 1944. Stands 98" end to end and 6" wide at hub. Beautiful wood! This propeller is in excellent condition and is does not have any "negative" markings from the FAA as most did when removed from their airplanes. This is a one of a kind find.
