So I contemplated the fact that the typos in the morse text and the copperplate text were intentional and could indicate a word or clue that would be useful. Sanborn has stated that they are intentional misspellings and that their position is important. I was unable to find anything useful but it was worth a look.

Something else that is worth a look is the Army Field Manual of Basic Cryptanalysis from 1990. I’ve started working through it and for any of you who are not cipher/code experts it would be well worth your time. I think the fact that it’s from 1990 will also help keep it relevant to what Sanborn and Scheidt would have likely tried.
