Back in the 1950s, Alvin Corp needed a small observation aircraft whether that be a plane or helicopter. In the end Alvin found a perfect helicopter to modify and turn it into a proper observation aircraft, they took a Bristol Sycamore and changed the body shape to be more appropriate for observation purposes. Alvin also added a more powerful and torqey which meaned they had to make the helicopter taller and wider to be able to fit the huge engine, also thanks to the increase in size, Alvin were able to add more equiptment and avionics which make it more advanced than the Sycamore. Primary users of the helicopter are Australia, United Kingdom and the USAF ordered a couple for testing and also converting them to ground attack fighters. 1 for lights, hope you enjoy.
