Early Wurlitzer keyboards — the 112, 120, and 140-series — have built in leg storage. The outer lid (which is hopefully still present all these years!) has a space to firmly screw in the legs, as well as a little strap in the center to hold them in place. This is probably early Wurlitzers’ most underrated feature!

The Wurlitzer 112 has a mysterious octal plug that appears to go nowhere. It is very similar to the wiring harness plug, except that it doesn’t end in a wire. It’s just a little black dome that occupies chassis real estate and doesn’t appear to do anything in particular.
