Why I think Cobb wasn't printed with a Brown Hindu back

To me there's some evidence they did it with some brands, especially in the 350's where there are shared groupings of prints/no prints.
The big brands, Piedmont, SC and maybe a couple others were probably produced almost continually, while others like the SL groups were probably on-offs at first.

That's why a ton more study of the tiny details is needed.
For example, on a simple one.
The Hindu and original OM Sl players were probably printed from a common set of fronts. If we examine a lot of fronts closely, we will either see no difference making a point for a single front press run getting two different backs. If we can tell the difference, that would almost certainly prove each brand got its own front plates.

There being probable different presses and locations makes it all the more complicated. But the place to start is with the more finite groups.

But I think there's to much jumping around with the backs when you start comparing them. there are some subjects when compared to another was printed with all the same backs except 1 or 2 if they were done with pre-printed fronts what happened to the one or two backs one of the subjects wasn't printed on?

On the other hand if you're saying that they printed up a bunch of fronts one day and then used those sheets to print 3 or 4 different backs the next day and then the process started again a couple of days later I do agree with that.
