Can someone identify this 20 x 110 Hispano projectile? It shows up in Spain from time to time, so I think it’s safe to guess it was purchased by the Spanish Army (more specifically, the Spanish Air Force, which used Hispano-Suiza AA guns and also aircraft guns, I believe).
Karl R. Pawlas in his book (1) shows a drawing of this projectile and says it is an API load with both nose and base incendiary loads and both nose and base fuzes. I can’t recall having seen another projectile with two fuzes.
The “226-54” stencilled inscription on the projectile must be the lot number and the year, but what does it mean the “N17-H” engraved in the projectile body?
