Note shell has space for six pins, but 5 have only been used. Part of a council master system me thinks. 2 anti drill pins in shell. 4 multi-mushroomed driver pins and one anti drill driver. 1 anti drill top pin and 4 standard brass top pins. plug has 2 anti drill pins one of which is next to key. If they made a snap proof version (i.e. just put a slot in the cylinder like multilock or squire snap safe), this would be an excellent product.
