Guess anything is possible. The Astra is a Spanish manufactured pistol. The Germans were involved in the Spanish civil war in the 1930s. They pretty much used the war to test their war machines, especially aircraft. Spain did extend limited assistance to the axis powers durring the early days of WW2. Who knows? In German "feuer" means "fire" and "sicher" means "safe". The markings are French, with "Feu" meaning "fire" and "sur" meaning "on". Maybe some frenchman gave it up to a German-------

Oooooops, forgot the question! The Astras are reasonably well made pistols, with the exception of some that were of questionable metalurgy in the early manufacturing process. It's not likely worth more than a hundred bucks or so to someone who collects. If it is in sound condition, it should be an "ok" shooter.
Hope this helps!
