"the 9.6.15,
Dear Fri (friend) Heinrich!
Have received your photograph today, it's worth keeping. Thank you for that. This is the second guncrew. Otherwise there's nothing new. To our left was a strong but unsuccessful Fri (French) attack. With best wishes I remain your friend Heinrich"
The 04/12 is identified by the additon of splinter shield. This is only the 3rd pic I've seen of the 04/12. Excellent find !
