Where are the wrongbacks?

I know this will be a bit controversial, AND it's another T206 thread, but I've been thinking about this for a while.

With T206 we've seen just about any sort of printers scrap possible, blank backs, missing colors, upside down backs, colors way off registration, multiple backs, even ones with trade cards on the back.

Without getting into the specifics of cards that may or may not be rebacked, there should be wrongbacks.
And someone will say it's impossible to tell, because the backs are generic and each front can be found with several backs. And for most cards that might be true.

But as a scrap? Say a sheet of 150 series that had some flaw that caused them to leave it unfinished may have been used to setup the press for the 350 series. And possibly that sheet could have gotten into the stack to be cut and released.

So where are they?
I think we've finally seen one with the Schulte that's been discussed recently. A subject with only 150 series and Hindu backs, unaltered, but still with a 350 back.

There should be others, other 150 only cards with 350 backs, or 350 only with 350-460 backs.
