Wiener Opernorchester

This is an ambiguous name for one of two Vienna opera orchestras:

- in English, The Vienna State Opera Orchestra
- in English, The Vienna People's Opera Orchestra, or The Vienna National Opera Orchestra

The first is more likely, but it's worth checking other versions within a master release if the identity is not clear.

The name may also be chosen to deliberately make credits more obscure: one sign of this is the use of known bogus artists, like Alfred Scholz and Henry Adolph. In this case, use Orchester Der Wiener Staatsoper (2) or Wiener Volksopernorchester (2).
