The ordnance QF 2-pounder was a British anti-tank gun that was also in many tanks and armored vehicles during world war II. Thanks to tri-pedal carriage, it was possible to lead the fire at the range of 360-degrees horizontally. Gradually, it was replaced with a 6-pound version. With the block version you can build a replica cannon with covering. A barrel with covering rotates round its own axis and moves up and down.
