I am in possession of a music box instrument produced by F. Rzebitschek
(Prague), serial no. 41236/3714, which is fully functional, although in
need of a cosmetic restoration, as the brass has taken a quite dark
patina.  Therefore I am applying to your expertise with the question
whether said piece is of any historical relevancy in the context of
music box instruments in order to judge its value.

I thank you for your efforts and remain
yours sincerely,

Jean-Marie Détrez
