Not sure about the 50's models but in the 60s 220s the crank is held on with a screw in the center. The plastic cover trim piece slides off - you need to kind of pry it up and slide it along the crank. Then the screw which holds the handle on is exposed. When you know how to do i you can take one off in a minute.
