On these older German engines, whenever you see brass piston rods, they're worn.
The nickel plating is worn off. The plating isn't that thick, but with the plating
gone the brass which is softer, wears faster.


Does this cause power reduction because the steam is escaping past the piston rod seal to the cylinder cap?
