John, the 320 and 385 engines at least as far back as the 6th series used aluminum pistons with 4 rings; whether this continued all the way to 1939 on the Super Eight I'm not sure w/o checking the parts book. Cast iron pistons were used in 1942 as the war curtailed the use of aluminum. Is this perhaps what you had in mind?

PS - sorry for responding John, I see you only wanted comment from Rusty.
