    A Pine Tree member provided me with another 15 HP powerhead and it has the factory ring in the lower seal area.  It is still in place and must be stainless steel as it is still shiny.  I will use that crankshaft and hope the ring remains in place as it has since 1956.  Notice the photo shows the interface between the factory ring and the crankshaft.
