I've heard the same but doing searches does not bring up much. I also tried to find the specific barrel length but had no luck.
I would be happy if it was an European model, then chances are good it is not a older design. If this is the 4 port or some post-64 version I don't know if I want it.
I asked here because I am a bit shy to ask sellers stuff like "is this the old version?". I hope some more info comes along.
All the best
