I'm sorry I cant tell you how to determine where the mic was made, but I've read and been told that if the Rode was made in China, avoid it.......if it is new enough to have been built in Australia, then jump on it.
I'm a big fan of Aussie-made Rode mics. Sure, they might not stack up against your Neumanns, but as far as bang-for-the-buck goes, they really are superb!
I have an NT1-a, NT2000 and the original NTV. I mainly use the smooth 2000 nowdays for recording vocals and sax, unless I want a brighter, rockier sound when I'll grab the NT1-a.
I reserve the valve for my own vocal use
