I have a nearly new Scott Atwater propeller in original box available. Box label was originally stamped 3645 3141, but someone marked a 37 over the last two digits, making it 3645 3137. It is 2-bladed, lefthand rotation, painted Scott Atwater green c. 1955, and looks about 8 inches in diameter. My bet would be for a mid-1950s 7.5 or 10 horse. Can send pics if interested. Asking $50.00, shipping in the U.S. included.
