Vintage brass boat propellers. I have two 3 blade and one smaller 2 blade. All the propellers show wear and marks throughout. The smaller two blade is marked "Michigan" and then some numbers that I cannot make out. It measures approx. 10" x 4". The 3 blade on the right has a few dings in the blades. It is marked "12163 454" on one side and the other side has several numbers around the centre. It measures 12" x 2 3/4". The 3 blade on the left has a few dings in the blades and there are some tiny paint splatters on it. It is marked "J29". It measures approx. 12" x 2 1/4". Please pm me for additional pictures. The propellers are $50 each.
