Answer
Greetings

You have an ammunition box for a 105mm artillery piece.  
The term DUALGRAN indicates that the propellant is made in two sizes.  The M2A1 and M2A2 are World War 2 era weapons.  The M103 and M137 are Vietnam era weapons but all 4 types could fire the type of ammunition in your ammunition box.  The US supplies these Howitzers and ammunition to dozens countries during the cold war along with the IS army and US marines using these weapons.  The box was made later 1960s or early 1970s; not 100% on that.

I hope this helps and check out links
