    Trying to find out what this came from. Lots of numbers all over it and it has a tapered bore. Please weigh in. It is also slightly ferrous. Looks bronze or brass so throws me off with it being ferrous.

      It is actually is a non-ferrous metal, "Propellers need to have very precise shapes, and be kept very smooth, for proper operations, therefore, a corrosion resistant material must be used, regular steel will not do. Brass is a cost effective alternative."
      "Important non-ferrous metals include aluminium, copper, lead, nickel, tin, titanium and zinc, and alloys such as brass."
      It could have come from anything.

      I see. That would explain the magnet barely sticking. Thanks for the information. Very Useful.
