Ain’t a glockenspiel. A glockenspiel is laid out horizontally, has tubular resonators, and is played with a mallet in each hand. The instrument shown is a bell lyre, strictly for marching, played with only the right hand because the left hand is needed to support the instrument. Since it is used only for marching, it is commonly played by oboe players, since oboes don’t, as a rule, march.
One also doesn’t usually encounter a viola in a band, but Sullivan called what he used in his comic operas a “band”, even though it differed from an orchestra only in using cornets instead of trumpets, so I’ll let it slide.
