The devices are normal in size. The dies may have been polished thus making the large dates devices may be looking smaller. But note on the image above for these differences.
1. The location of of the '2' on the date. The large date '2' is closer to the rim.
2. The large dates devices are larger than the small date.
3. Why are they different sizes? The large date was hubbed from a swelling master hub. When they noticed this they recreated a new master hub. The new master hub was not swollen so the devices are in the normal locations. How can I prove this is what happened? But using the small date design.

This is what the new master hub passed down the chain of command would create. (What does this mean? The chain of command?)

The steps the master hub to working die progression happens. The design is part of the creation of the dies and hubs are created.
Back to the differences of the large and small design differences:
Note the locations of the devices? That is what the design should look like. But using Photoshop I can create a movement of the design to more towards the rim.

Note the change on the second image? Seeing them side by side will help a bit more:

The movement of the devices are seen moved and enlarged, just like the normal large dates images on this re-creation.

Side by side a breakdown of the differences can be seen:


The differences is locations and sizes of the devices. sorry to go this deep, but to see the exact differences, helps you to ID these differences in the future searches.
