Piaggio P.XIX

 

The Piaggio P.XI was a licensed derivative of the French Gnome-Rhône Mistral Major 14K produced in Italy. Isotta Fraschini also produced a version of the 14K called the K.14.

Further development led to the P.XIX. This featured an increased compression rate from 6:1 to 7:1 and rpm from 2,400 to 2,600.
