The American accent T’nA James’ production/distribution numbers are nearly impossible to trace and It is identical to the Japanese and British versions, so identifying one relies on having to hear it’s voicing, which is an extra hoop to jump though and not always possible as some people cannot differentiate from accents, not working, etc.
The packaging between the three is all different, but once it becomes loose without a box it is a crap shoot to find one.
There is also only one known US James still with its box.
