Yours is definitely a 221. If you put the machine so you can see the underside, you will see the numbers of your machine. Then go on line and check to see what the date is. It goes by the first letters. In otherwards mine is AL. As for the case everyone is right, the outer fabric has been taken off and refurnished. Looks good. When I went to Sisters Outdoor Quilt Show and Quilters Affair a few years ago, I saw a case that someone had done decorative sewing things all around the base of the case. It ws just darling and everyone wanted to know if she did it and if not who did so they could get theirs done. It has scissors, tomato pin cushion, rulers, irons(old antique ones)rotary cutters, etc. Just as cute as can be!!! Jan
