The new piston head castings have been machined and the core plug / stays fitted and peened over. Here the head has been fitted onto the piston rod and the nut and lock nut tightened and the new tab washer hammered over to stop them from unscrewing. The nut is right hand and the lock nut is a smaller left hand thread.
