Note all these pictures are
showing piston #3 that has been thoroughly cleaned, because this required
the use of a brass wire brush some fine detailing of the detonation pitting
has been lost. There is also some damage from the piston being handled to
remove the grime, pin and rings. Also note these pictures are high
resolution and around 400kb in size.
