Silva-Bet is a trade name used by the Cundy-Bettoney company, a woodwind maker and distributor in Boston, Massachusetts.
[1][2] Shortly after the appearance of the Silva-Bet, other woodwind makers entered the metal clarinet market, including Selmer Paris in 1927 [3] with their Master Model as well as American companies Buescher with their True Tone model and H. N. White with the Silver King.
The toneholes, except on the earliest examples, have widened tops to improve the sealing and durability of the pads.
Earlier examples of the Silva-Bet have serial numbers beginning with S, usually followed by four digits.
After a kind of backlash against them in the mid-to-late twentieth century, metal clarinets have returned to favor in some quarters.
[6] They also produced many, many stencils marketed under other distributor's names, including Martin Handcraft metal clarinets.
