I take it that photo came from the Spanish civil war, where the Germans supported franco'e nationalist forces.
The Spaniards have made some interesting guns. I once had a 10 guage double barrel, made in Spain.
I saw many a GI buy a Llama or Star pistol, for their own use. More recently, I bought a "Spanish Destroyer" carbine. A resl handy little carbine,
meant for the national police of Spain. It is chambered for the 9mm Largo.
I had in mind to use it as a short range coyote/groundhog gun, but my grandson..the arms expert/collector liked it so much, I gave it to him early.
Text says it replaced the El Tigre..
