The Spanish don't count!
They never bought any- and Ala 12 ( I think) only operated them for a wee while. They were then returned to the rightful owners, I expect.
There were no 104s that were 'Spanish' ones.
That said, I can't remember whose aircraft they borrowed. Think it was from the Germans???
Certainly, the one in the Museo del Aire at C-V, which is half painted as Spanish- is a Luftwaffe example- although not one that temporarily served Spain, I think!
I stand by my assertion that the Noggies were the safest.
