Hi BellaBoo, I have a 221 Featherweight too. I just love it!
I had to throw out the case though. The sewing machine repair man that checked it out for me said that all of the cases have a mildew odor because of the fabric and glue that they used at the time they were made.
The machine is a gentle giant - works like a horse but purrs like a kitten.
Lucky you!!!!!
