The title should have read Maxwell-Banks.This prop is in like new condition and appears to have never been mounted. It is 66" in diameter and a pitch of 44 and has 30 laminations. The company started in aircraft props in 1936 as far as I can tell and then went to props for air boats and snow sleighs pre and post war. This prop is absolutely beautiful in condition and craftsmanship and could maby be put into service or used as a classy vintage display in your home hanger/business. Mount it on the wall or electric motor and have it spin slowly.
