In Tanks third and forth shot it looks as if it has two screens on it, the dome shaped one and then the round flat one, could it be that they were trying to keep the cinder fires down back then too? Double protection at it's best. Since we are on the subject of cinder arresters, why didn't the D&S go back to the Bear Trap design, was in not as efficient?
