AFAIK ,, it is in very recent years that ALPHA Industries moved M65 manufacture to China , so in theory a modern manufacture OD jacket was identical to Vietnam war era. - the price was very reasonable. So unless you wanted something A1 cleaned with somebody elses name on - what was the point ?? I suppose here are rivet counter clothes collectors.
Actually - abt. 5 years ago , I wanted a Nightime Urban , the very best deal was that I imported a small batch direct from USA , marked X'mas present - no £ duty this end..
