I had the 327k, predecessor to this machine, for many years. Got it in 1964 as a HS graduation gift. It was very easy to use and take care of. Mine did not have the capability of taking the cams, but did a nice zigzag stitch as well as a good straight stitch. Looks like the main thing you are missing is the 'hood' over the light. Not sure if that went all the way to the 'gold' cover or if there is another piece that should be there. I think you will enjoy this machine.
