British Type 22 Pillbox FW3/22 - WW2 Bunker - STL

The Type 22 pillbox was a small British fortification for riflemen that was designed and constructed for the expected German invasion of England in world war 2.

The official designation of this bunker was FW3/22 and had a hexagonal shape with a 10ft internal diameter. The people inside had loop holes to shoot out of and the troops were protected by means of a small entrance with an internal blast wall.

The loop holes were not made to any particular standard and took a variety of forms however they were up to 600mm x 600mm and were formed with metal or wooden boxes that the walls were cast around. Sometimes they were edged with brickwork. Some models had internal shutters of metal or asbestos and a there was often a shelf on the inside for a rifleman to rest his gun and extra ammo on which were often hinged
