This Casa 1.131 was one of three Jungmanns in the Tenerife Aero Club.  E3B-113 as seen below is one of them.
 
 
Francesco writes : “ Going from Tenerife to the auxiliary aerodrome of El Medano, very close to the South Airport, Reina Sofia.  It can be seen that in those years this part of the island was pure desert and communications by land were poor.” - Sept 1960
 
 
“It was a joy to have three aircraft at the aero club. I (Francesco) took this picture while flying next to the mountains of Tenerife.” Feb 1961
   
 
As mentioned earlier, there were three Buckers at the Tenerife Aero Club.  All of them were painted silver with paint on the upper part of the engine cowling and an arrow down the side - one Jungmann was blue, one was red and the other green.
 
 
The airplane lives in England today and flies as G-BIRI
