Spanish mates help (I need the)

[Enrico Cernuschi]

Good evening Gentlemen,

I need the help of Spanish forum mates or, maybe, by some experten about the Spanish Civil War.

Did the Spanish Nationalist flying boats and floatplanes of the Cant Z 501 and 506 types claim any success against enemy or neutral freighters at sea in 1937-1939?

Thank you for any suggestion.

Greetings

EC
