My catalogue is of very little help, here`s the picture:

Maybe my eyes are untrained but these two look the same to me. As I have a short set (2c to 16c) they might be die 2 (catalogue says the 48c& 96c come only die 1..?)
Here are the last 2, could somebody explain me the difference (I`ve tried the internet but found only small pictures of both die 1 and 2)
