Any other brands?

Depends on what you consider a "company" and what you consider a "brand": Courtois, Meinl_Westaon/B&S/VMI (and possibly Gerhard Baier) are all JA Musik brands; Besson is a Buffett-Crampon brand, but are mfg'd in a JA Musik factory; so it could be argued that they're all manufactured by the same company.

There are any number of house branded 4-valce comp euphs manufactured under contract by Daylan and Jin Bao, including, but not limited to: Tuba Exchange, Dillon, M&M, Virtuosi, Helios UK, Rosetti, Wiseman, Eastman; and then there's the Australia-based seller who occasionally lists its house brand on ebay.

Two Continental manufacturers who make 4-valve comp euphs that are relatively unknown in the US: [l]Thomas Inderbinen]www.inderbinen.com]http://www.inderbinen.com/Page_e/Euphonium_e.html[/l] (Swiss) and Adams Muziekcentrale (Dutch).
