Fine workmanship. Very desirable instruments, especially for chamber music. Made about 395 violins, 15 violas, and 7 cellos.

"DAHL, MATHIAS M. - Born in Norway, 1888. Took an interest in violins from infancy-made his first violin at the precocious age of seven, being unusually talented with tools in the art of woodcraft. Went to the United States and studied the finer points of delicate work under H. P. Blakkestead (Minneapolis). Subsequently worked for the Blakkestead Music Company. Still active 1949. Made a thorough study of re- graduating, arching, and particularly varnishing. Took the usual interest in following out the Stradivarian model as closely as possible, and shows from what simple materials and means beautiful workmanship may be produced when taken in hand by one who knows how to use them to good account. Sound-holes, scroll, and purfling done splendidly. Whole contour so harmonious that it could not have been thus represented without great know- ledge of what art can effect, and without a skilful hand to apply that knowledge. Colour of varnish is Venetian red, shading from light to dark tints, together with an excellent filler which adds considerably to the tonal qualities. Produced about three violins yearly. Instruments. built for the future, and as such, in that rosy time for tone-maturity his productions will have a significance far beyond that of an ordinary orchestral violin."
