The model 122 cabinet is shown at left.  The 21H cabinet is very similar in appearance to a 122 or 147, the largest difference is that the upper horn speaks through only one level of louvers, not two as shown here.

This model was made specifically for the balanced output of a Hammond "G-G" Console (IE Model B or C).

It is interesting to note that unlike later cabinets, this cabinet featured an ELECTRO-dynamic speaker like 31(A/H/W).  What this meant is that the 15" woofer did not have a permanent magnet, like speakers have today, but rather a large coil of wire which acted as an electromagnet.  This coil was also wired in such away that is acted as a filter choke for the amplifier's power supply

** Power output differs depending on the amplifier version used.
