Have the same issue with the 3-piece piston of an old Bee engine..it really rattles due to the extended gap but I cannot help it.

There is a picture somewhere of one dissembled, they are actually 4 pieces, there is a thin ring that holds the assembly together.
Bob (rsv1cox) has a really good picture.
