Apr 29, 2014 · The eion 4W/N goes back to Mil-Std 167, first issued by the U. S. Navy Bureau of Ships in the early 1950's. At least that is what I have from some Navy documents from 1965. "W" in the Navy spec however was total rotor weight as opposed to journal weight as applied in API specs. Thus, for a symmetrical rotor API is 1/2 the old Mil, spec. RM.
