            The reddish colored bin at bottom left 
            holds the endless 5-tune music roll, which feeds upward through 
            the rollers and over the tracker bar (visible directly above the 
            red colored music roll storage bin). The electric motor (barely 
            visible to the right of the roll storage bin) is belted to the 
            pump assembly, which is located at the back of the machine. | 
        
        
            Two string picker assemblies are situated 
            on either side of the banjo, with the actual picking arms and 
            the tiny templates that describe their picking orbits supported 
            by the ornate nickel-plated metalwork. Each of the four 
            independent pickers is operated by a single, large pneumatic, 
            delivering a quick motion, with more than enough motive power to 
            do the job. | 
        
        
            
            Close-up of the left-side banjo picking mechanism. The two flat 
            springs forward of the pneumatics and ornate bracket offer 
            sliding resistance to the pivoted picker wires. This resistance 
            causes the pickers to follow "elliptical" orbits described by 
            tiny templates located about two inches inward from the banjo 
            end of the supporting bracket. |
