I service my pre 1956 machines myself, but took the 1973 Elna in yearly when I had a good repairman and was using her heavily for apparel and home dec. She doesn't get much use these days and there is no good repairman available, so it's been a while now. I will call the old repairman one of these days and see if I can bring her to his house. That machine isn't going to be touched by anyone who doesn't know what he/she is doing.
