Hey Chris, nice post again!
Would love to find me an Ottoman WW1 Kalpak similar to photo A some day!
What were the goggles used for by the 'MP' in photo E?
Also, I can read the last 2 words in Arabic on his gorget ('ASKARI KANUNI' or law soldier as you explained with askari= soldier & kanun= law) but can't make the first (some Turkish word written in Arabic script)...
