Fernando Siveris Xavier has sent some pictures of famous Brazilian aerobatic pilot Alberto Bertelli.
PP-TEZ was piloted by Alberto Bertelli, the leading ace of the Brazilian acrobatics. He died in his sleep during December 1980.
Your aircraft is today on display at the Brazilian Aerospace Museum.
It is one of the most beautiful stories of aviation that I know. Alberto Bertelli and his Bucker were inseparable.
His ability to fly the Bücker, mainly performing acrobatics, was so exceptional that it was the only CIVIL flying permitted in the Air Demonstration Squadron of the Brazilian Air Force, popularly known as "Smoke Squadron".

There are some Youtube videos of Alberto Bertelli's flying. I particularly like this one that shows just what could be done with the "standard" German airframe and 100 HP Hirth engine.
Thank you Fernando
