Hi,
I experienced a few times with the LH lost&found (once I finally got through) that they're really unwilling to care about these "problems". So far, neither one of my colleagues nor myself haven't got any lost item back. (varying from a pair of scissors (with name tag) in the security box to a child's stroller (!)) ...
Rgds,

P.S.: Different to that, Singapore Airlines two weeks ago was even able to allocate a colleague's lost item w/o even a name on it and returned it to him within 2 days via express mail.
