Wayne.................those props certainly look to be a good profile & design after cleaning
and for the style and vintage of the vessel, brass/bronze aged finish always looks better than
red paint
I certainly do not know the answer, however it may be best to research the direction of the props......ie., either inboard turning or outboard turning.... again I understand you are not sure of the exact Class of vessel, however I suspect most types of this general design would have similar handed drives.......Derek
