This illustration of a violin by Carlo Guadagnini was published in The Strad, September 1961. The following text is extracted from the article accompanying the photographs:

Giovanni Baptista Guadagnini is usually credited as having three sons who followed in this calling: Giuseppe I (Turin 1736-1806); Gaetano I (1745-1831) and Lorenzo II, but it now appears that there was probably a fourth son, Carlo. This Carlo has until recently been considered as the second son of Gaetano I and a grandson of G.B. Guadagnini.

Very few violins by Carlo Guadagnini are known. He is mentioned in Stainer’s Dictionary as being a maker of guitars and a repairer of instruments and this would account for the scarcity of his violins.

The violin illustrated is a handsome and well preserved example of the maker’s work and is original in all its parts. Carlo Guadagnini’s violins are built on the style of G.B. Guadagnini and the sound-holes and scroll, also the flat modelling, recall this maker who would most likely have been Carlo’s instructor.

The principal measurements are: Length of Body 13 7/7 inches, full (352mm); Top Bouts 6 ½ inches (165mm); Middle Bouts 4 ¼ inches, full (109mm) and Lower Bouts 8 1/16 inches, full (206mm).

The back is in one piece of native Italian maple with a small horizontal flame. The ribs are without figure and the head is of similar wood. The two-piece table is of pine of regular medium grain.

The red-brown varnish of excellent quality is a little opaque and slightly crackled on the table. Carlo Guadagnini applied his varnish more thickly than that found on instruments by G.B. Guadagnini.
