Britain's Bison Concrete Armored Vehicle added

Another type of vehicle that was developed and assembled during the time when at any moment the Germans might invade Britain was the Bison Concrete Armored Vehicles. These were basically truck chassis with a wooden frame built on them, then concrete poured over the top. This would provide some protection for the occupants from shells up to 37 mm.
Again, unfortunately, no pictures. If anyone has any feel free to send them my way.
