This diorama is scratch made. We used the newest World War One figures from FRONT LINE FIGURES to create this exciting diorama. The British are in the process of getting over run by the German soldiers. The barbed wire, trench, sand bags and poison gas alarm are all scratch made. The poison alarm is to the left of the entrance to the tunnel. The soldier would grab the metal bar and hit the empty shell as a gas warning. Oh, I also made the smoke clouds and explosions.
