WWII Luck Flag Translation

[Eightydeuce]

This flag was given to me by a veteran who served with the 11th Airborne in the Phillipenes Durring WWII. Ed was his name and he was in heavy combat as an airborne infantryman. As I understand it there were Luck Flags taken from individual soldiers killed and then there were those that were sold to soldiers. Would like to identify this one if possible. Its in rough shape is stained and what appear to be bullet holes in it. Any help would be appreciated.

This is the correct orientation

 

The big letters across the top read 武運長久 (būun chōkyū), which is basically "good luck in battle". 

The letters that go vertical down the right side are the recipient's name 贈　関口利夫君　Sekiguchi Toshio (not sure about Toshio). Sekiguchi is the family name. 

The rest are names and patriotic slogans. The flag was presented to Mr. Sekiguchi by his workmates at the company for which he worked. I can't quite read the name of the company. Some steel company, it looks like.
