Hey Ted, here is my breakdown of the entire 460 series.
The first group of 27 + 1 (either Dougherty or Ames) + the 6 superprints would make a sheet of 34.
The group 3 of 28 + 6 (either super prints, or your Exclusive 12) makes 34
The groups 4 & 5 of 21 + 13 makes another sheet of 34 (the one oddball is P42s are missing the 21, which is weird)
There is 34 SC 150 F649s, 34 Hindu SLs, 67+1 (Either Magie or Magee) in P150, SC150F25, SC150F30, SOV150 & Hindu. Its also very frequent in the 350 series but thats still a work in progress.
Why are the P42s missing the group of 21, how do we get a significant more Exclusive 12s in AB460, SOV460s & RH, did a group of 28+Exclusives get mixed in when printing the UZITS. This is what keeps me up at night
