HERING Gloriosa

GLORIOSA:

• straight mouthpiece
• key of E

Here is something I read on the internet about the GLORIOSA:

There is also a single reed version of the Wiener System, which could be called Halb-Wiener, or half-Viennese. These feature just a single set of reeds, often mounted on just one reedplate. Sometimes the comb is like the typical Viennese harmonica, but with half the chambers empty; other examples have just a single row of holes in the mouthpiece.
