Hello Stephen, possibly you can retrieve those files from that CD still.
do a search on the net using words like : CD recovery, lost files on CD or Disk Internals CD & DVD Recovery.
worth a try I guess. succes.

The disc in question / that is if Robb had managed to make a number of them - contained many chapters of information & instructions on maintenance & repair of bsa m20’s
It’s not Henk’s disc
Robb had created a series of PDF documents which covered various sections of the bike - frame, when’s, gesrbox etc
I noted at one point he said he was going to place them on a disc & was going to charge a small fee for his time & effort
He had cad drawings etc of some items & this is what Stephen is looking for
