Yeah, this is a lot for me to wrap my brain around
It seems to make more sense to me that all 48 SL'ers would be in the same print group. For a minute, while pondering the idea that the 14 subjects not printed with Hindu were printed in the second print group (350 series), I thought of the 14+14+6 (like Steve mentioned above) and wondered "well, a double-print on the 14 subjects and maybe the 6 super-prints?",,,,,but the OM on these 14 subjects kills that idea. It would only work if you were talking Piedmont.
I really wish someone would find an intact sheet
Maybe Mastro has the answer
The Obak sheet comes to mind (I know, Obak's weren't printed by the ALC).
I love this type of discussion, thanks !!!
