RCA CTC-7 Worthington: Where are the legs?

[Adam]

Here's a crazy idea. Could that lower part of the legs have been somehow detachable? Look closely at this picture here and notice how there appears to be a straight line across the leg below which the wood appears darker, making it look like that lower part which is missing on the other set is actually a seperate piece of wood. I don't see it on the other leg though.
