You can help this machine with french polish. You will need denatured alcohol and linseed oil. Use the technique as described only start with alcohol and oil (stay away from the decals). Dip cloth on finger in alcohol and then add a drop or two of oil. Now lightly go over the crazing in a circular motion smoothing out the crazy. This will take some time and may take longer than a day or two. After the finish is to your liking you can proceed with the shellac french polish to shin it up. I recommend you practice on an old machine first. Remember to move fast or your cloth will stick to the surface. You can also sand with fine wet or dry sand paper and sewing machine oil to smooth but don't cut thru the black finsih. Then french polish with shellac several times until the finish is even and shiny. Please read the instructions carefully and practice on an old machine before working on your good machine.
