I still have, but no longer use, the old Elna Superior that I got in 1953. I then progressed to a Jubilee, which is a workhorse and a half, then to the 6500 and now have the 8500 combo sew and embroidery machine. The only work ever done on any has been cleaning. They have been the most trouble free machines I have ever known. The original Elna uses the cams for decorative st. My we have come along way!!
