Got the baggage lost and found phone number from the WC when we were on our return.
Was asked what flight, day and seat. put on hold for a minute or two, and they came back with the news that they did have it, and would deliver it to my departing gate.

Wife is happy to have her camera back, had som pics of the grandkids on it. She will just have to look at the pics that >I< took in Beijing.

Thanks to all for answers.. and a BIG thanks to the Narita NW crew.
