Forgot external hard drive on LH415

Cheers,

I flew on LH415 Wed night, arriving MUC on Thursday. Unfortunately, I forgot my hard drive (together with my laptop charger) that was packed into an old LH amenity bag at my seat. I have already contacted MUC lost&found, but nothing turned up.

Are there any other places I should contact, e.g. AIMH’s next destination if it hadn’t been found during cleaning in MUC?

Thanks much :)
