The first letter at 6a will blow the endgame, hankir (it's from the 2nd half of the alphabet, as is the different one that starts 39ac) but I'm happy to reveal it if you're sure.
Last word of misprints is 7 letters (starts with 13d).
I meant 39a. What does it start with?
I thought 6a started with F.
This is how I am interpreting the last word from misprints:
Nato alphabet.
Play in which 6a appears.
