Dear Mr. Sacher,

The score of the Martinu SINFONIA CONCERTANTE is now with me after the parts have been copied. However, there are quite a few doubtful instances – as you know, Martinu is sometimes  a bit careless in his handwriting. For this reason we are now preparing a list of queries which is going to be sent to Martinu. I shall send you the score immediately and I shall also advise you of his answers as soon as he replies.

                              With best wishes,

                                            Yours sincerely,

                                                           [podpis]
