Almost all chinese subminiature tube microphones (also the Tbone one) I guess are copies from Aspen Pittman designs for Alesis / Groove Tubes tube mics, take a look at them. The tube they use were 5840 or 6205 (almost the same tube).

2001 can't be the tube production year btw, maybe of the mic...
Any more pics?
