Dear Rick Cooley,  As a matter of fact, we have restored a large range
of music cardbooks, from Hooghuys to Gasparini, or Gavioli and of
course Limonaire.  We are established in the south of France.

We proceed first by scanning, then we recut new cardbooks observing
the same material thickness.  At the moment we cut square holes;
however we are able to consider round holes.  Maybe we can be helpful
regarding the restoration of your 80-note Bruder cardbooks.

Looking forward to hearing from you,

Best regards,
