The second drum is a one piece cast drum with a sleeve bearing race for the smaller 1936-48 wheel bearing (68-1225-A). This drum was also only used in early 1936 production and then later superseeded by the common 1936-39 wide five rear drums we see all over. Maybe it was superseeded for cost and/or quality reasons because I believe it's easier and less expensive to cast the later rear 1936-39 drums.
