I was mainly looking at the IGWT, that's the only "doubling" I thought I saw. But as I was looking closer doesn't it look like there is doubling on GW's ear? Also, I don't have another one of these so I can't compare it but the 2 S's on the back look different, not sure if that's normal.
But that is not an ear. These are the multi-hub dies back then. Most of the doubled dies are found on the outer devices. These are Denver examples, but I included them so you will see what areas to see hub doubling compared with a normal die example, side by side.
Note how much wider the doubled dies are? Note the centers of the closed devices? ('B' and 'R') See how that are is reduced because of the hub doubling.
