"In the body is a black seal which stands for the combined coat-of-arms of the Prince and of his wife, who was born Countess Maria of Strassoldo. The Princess herself was a violinist of no small talent. . .
When Professor Popoff acquired the instrument it was still in its original condition and even had its original neck; however, he had the neck changed upon the advice of a violin-maker in Moscow, because it was very much worn and made playing somewhat difficult.
The original neck is still preserved."
