Don't Japanese delivered machines have a metal Taito badge affixed to the headbox artwork? As per this Japanese MM below:


IJ:

4-4.5 for a  standard container job with cab fade.
5 and up for a well looked after with minimal cab fade (add $$$ for aftermarket mods - gold siderails and lockdown, aftermarket toys will quickly add up).
Could easily get to 6 and above for a FULL restore with the works including redecal (just based on what is spent on parts alone, ignoring the labour/time of a proper redecal and restoration - yes, been there, done that).

It has and always will be a popular title and looks stunning once given the restoration treatment.
