Do we know when Classics started leaving the factory with backlit handsets and the new battery box? That could be a split point, though some incidents on units after that could have been on unmodified units (and clearly were). <snip>
Thanks for offering to do it. Any chance of going back to your confidential source to ask for permission to do it?
Cheers,
There is no chance the confidential data would be released to be used outside the Chinese wall, unfortunately. This means we know data exists, but cannot use it at all, refer to it etc, other than for the specific purpose it was released to us. This is fairly common with most NDA agreements or arrangements involving confidentiality.
As regards the backlit handsets: all units after Aug 2000 were backlit - I know this because I recommended many of those changes directly to APD from April 2000 building up to a peak in May and June 2000.
Battery boxes from new were Dec 2003 from our own figures.
However, what we do not know in many accidents is exactly what the configuration was: backlit of not is known in some accidents but not others, battery box type known in some but not others etc.
