The Bundy horns were named after George M. Bundy, a friend of one of the Selmer boys and one of the designers at Selmer (USA) during the first half of the 20th century.

There are several iterations of this horn:

THE CONN CONNECTION: Because Conn owned 49% of Selmer (USA), the first Bundys were Conn or Buescher stencils. They had elaborate engraving and play fairly well, more an "advanced intermediate" horn than a student horn.

KEILWERTH?: In the 1950's Selmer had Keilwerth stencil some Bundy (no rolled tone holes) and Bundy Special (rolled tone hole) horns for them. These are, by far, the best Bundy horns out there. They're marked, "Made in Germany" and have a funky plastic keyguard (if it's not broken off). If you find one of these horns BUY IT. They have exceptional quality, intonation and workmanship.

BUESCHER, REDUX: In the 60's, Buescher was bought by Selmer and became the producer of Selmer (USA) horns, producing several iterations of Bundy horns, including the world's most popular student horn, the Bundy II.

My opinion is that the Bundy II/Selmer 100 horns are decent and are very rugged (you can run one over with a tank and it'll still play in tune), but the best sounding and playing student horns currently being produced are the Yamaha 23's. However, if you think that the horn is gonna be significantly bashed up, get a Bundy II.
