Spandau was the arsenal where it was made.I'm not a mil-surp guy... But I've been a "gun guy" for nigh-on 20 years now. And I don't think I've ever even HEARD of a Spandau! Nifty.
What caught my eye was that the receiver is still in the white, that's not very common for an 88/05.Looks like a nice one, matching numbers is pretty unusual for one that went to Turkey. Great find!
