You should take a look at the motor. There is some advantages to having two hands free when maneuvering seams and fabric. The hand crank can give precision stitching, but in the long run it's usually the machine with motor and lights that gets any use. Your machine looks like it's in very nice condition and it will probably polish up further, it's wirht to have it intact. Needle and presser bar polish up like new with the right stuff (like quick-glo). Be a bit careful when handeling the top tensioner. White had these very fancy tensioners on some models, and it has turned out very difficult to get them back together if taken appart. Cleaning and reassembling tensioners are usually easy, but yours might be an exception. There aren't any tutorials or service manuals available for how it originally was done either.
