This propeller appears to be a Dewald made prop due to the name Dewald etched into the hub.  It is a steel two bladed prop that is 6.25" diameter and unknow pitch.  9/16" shaft with a 0.15 shear pin hole. Markings on the prop besides Dewald are AULC, (maybe meaning long course) number 4659 etched in the hub above the name, stamped into the hub V757, S, ??02+, 56.  What all of that means I do not know. The prop is in very good condition and appears to be for a KG4H or KG4Q or a Mark 15 on a Quicksilver racing tower and foot.  Shipping and insurance will be added before shipped to purchaser.
