Pre 2009 Warwick Basses with the 2 piece 3D bridge are normally German. The bridges on all other non-German Warwick basses in the earlier period where cheaper one piece bridges (Corvette Std's anyway).
Also I dont think they made any non-German basses with the ovenkal neck?
The one thing that did throw me off it being German initially was the black Nut, but looking at the fact the rest of the hardware is black im assuming the brass Nut is painted.
Get more pics?
That age German Corvette will have the strap-locks built into the body, as oppose to them now where they are protruding (so you can just attach a strap without the locks, in the normal way)
To be 100% sure, get the serial number!
