Most likely, it's an earlier US made cab, because 95% of the time that is what comes up for sale. The German cabs are still pretty new, and don't come up for sale much.
The dead give away is the silver piping around the grille. The US cabs do NOT have this dressed up feature. Notice the piping in the pic of mine below, which should give you an idea of what to look for.
The last thing would be the V30's, most of all of the German made cabs come standard with K100's. Of course, someone could have done some speaker swapping, but ALL V30's would hint to me US made.
