The late style drum shelf in style G #54,529, made in 1922. The cymbal is to the left, the triangle is to its right, the snare drum is in the middle with the beater in front and the snare damper pneumatic in back, and the bass drum is in its usual position to the right. This style has two pneumatics next to each other on the top of the left end of the shelf, between the pressure reservoir and cymbal. One is for percussion soft and loud, and the other turns the drums off when a small brass knob on the front is turned to the soft position. With the pneumatically-controlled percussion on/off mechanism and external knob, there are no internal manual switches as in the early system. The pipes in this example are harmonic flutes with nodal holes in the front row, and maple-front violins behind.

Two knobs on the front near the left side of the case, for manually turning off the pipes in a late style G. Two similar knobs are on the front near the right side, just above the coin chute, for turning off the drums and setting the expression on soft.

Late style drum shelf in style H #54,153, also made in 1922. The layout is similar to the late style G drum shelf, with the addition of a castanet mechanism between the two drums. The two pneumatics for drum expression and turning the drums off manually, as in the late style G drum shelf, can be seen on top of the shelf just in front of the cymbal (see inset). This style H has control knobs on the front, near the left and right sides as on the late style G. The two on the right side may be seen just below the coin slot. Other late style H orchestrions have all the knobs mounted on the right side of the case.
