This illustration of a violin by J.B. Guadagnini was published in The Strad, November 1938. The following text is extracted from the article accompanying the photographs:
This instrument was made in the year prior to J.B. Guadagnini’s removal from Parma to Turin. His stay in Parma lasted for ten years and would appear to have been a fairly successful phase in his career.
The violin illustrated has a one-piece back, though most of his instruments had two-piece backs. It is a well-preserved specimen and is generously covered with a dark red-brown varnish which has become artistically shaded through wear and time.
The body length is 13 15/16 inches, which is usual for his instruments. Other dimensions are: Upper Bouts, 6 9/16ths inches; Middle Bouts, 4 ½ inches; Lower Bouts, 8 inches full; Depth of Ribs, 1 3/16th to 1 ¼ inches. The violin bears its original label dated Parma, 1769.
