What's the story on the Muskegon Corp in Detroit ? where they the original company that was bought out by Dana Corp in 1988 and the name changed into the Sealed Power Corp ? anyone know the history ? reason I'm asking I picked up a set of new Sealed Power pistons (H521NP30) in a Muskegon box . 
from what I gather they made aircraft engine parts , piston rings , pistons , camshafts , bearings , etc .
