I just picked up a 328 at an Estate Sale. It doesn't have a light switch. It is in a portable case, but the latch on one side is broken. For the life of me I can't get it out of the plastic bottom case. I wanted to clean it and oil it. The machine itself doesn't really look used.....not a scratch, however, there was sooooooo much lint packed in around the bobbin area, I know it was used a lot. It is rather loud..........another reason I was wanting in there to oil the bottom. It came with some cams.
