You are welcome to send the disks to me to dump to ADF images and I will scan the disks/labels as well. I will gladly return the disks to you if you wish.
I am not connected to AMR, but as they are not renowned for their quick response to offers of this kind you could be waiting for a long time...
If the disks do not give up their data easily, I have a number of data recovery techniques that I can use.
I have previously dumped disks for bLAZER and hitm4n.
Let me know, and I'll PM you my address details if you wish to go ahead.
