I would agree that it appears there was a chip in 2002 but not in 2001. The only unexplained thing is why a 2001 chip was listed in TCR in May 2002.

It could be a mistake - it could be a duplicate entry for 2000, but then it would have been stated as LE666 which it is not. It was 5 months too early to be 2002!

I have to say the chances of Mark replying to my email are remote - perhaps someone else should try him??
