[LargeFormat] B&W film of the 40s

[Les Newcomer]

It's 1943,  6 months ago you back at home trying to figure out where to 
take your sweetheart next Friday.

But your in the war now.  You're part of a Signal Corps Photographic 
Unit.

Uncle Sam gave you free training, a colt 45 side arm, and a Speed 
Graphic.

Just what kind of film is in that camera right now?  Pack film, for 
sure, but it won't be Tri-x would it?

Might it be ortho?  Hey the flyboys use that stuff to cut through the 
haze, but would ground troops use it?
