WW2 DEMOLITION PLATOON CHEST

[Jake Mohawk]

Hello, i have this demoliton platoon chest I have noticed that it has several markings and I don't know very well what they mean. If someone could help me, I would appreciate it. Here are some photos of the markings mentioned above.

 

In some images I can see inscriptions that say demolition in red, I also see a big red one, I would like to think it's from the Big Red One, I also see in another photo the symbol of the engineers, the red castle with a yellow stripe

 

This copper was found in northern France
