The predominant line manufactured by The Autophone Company was that of The Gem Roller Organ, their least expensive model. A typical pressure model continued the simplistic design of the pedestal leg Gem, but added side panels to cover the bottom feeders. The clover-shaped cutouts were similar to the Pressure “Box Case” models. The design incorporated the same sound quality as found in the enclosed models, but in a simplified, inexpensive case. The dark finish allowed the use of inexpensive native lumber with minimal cost. With a retail price of only $6.00, it is estimated that tens of thousands of this pressure model alone may have been sold. It remained the sales leader until the advent of roller organs operated by vacuum, rather than pressure.
