More history. Was it used by the Military, Police, etc? The serial number seems to be very odd compared to the few others I could find anything about...why? Why did it stop production? How realiable is it? How many were made? Are there modifications that I might want to consider? What's the value of it?What do you want to know?
There are a few tables that I know nothing about listed in your response. ANIB, EXC, VG, and some others. What do they represent? Also, the serial number doesn't seem to fit what is listed starting with TDF0501-0972 but had started wtih TDF0001 What is stamped on mine is TZT0120.
