Ibanez switched back and forth between Edge and Lo-Pro. You can't guarantee they'd use one or the other. There's also a chance it's been swapped by the owner, as either one would slot right in, although I think that's the original trem on there.
right, althought there are signs that allow us to get a closer range:
#F9751807 + AANJ + V7/V8 + moved volume knob = 1997
