What have you got to lose for ??free? I still have my old 64 Elna which would be the same era and I sewed on that machine for over 30 yrs. It has never seen a day in a shop. I always cleaned and oiled her myself and to this day, she runs like a charm. She uses cams also. My neighbor who had 12 children had a Viking free-arm and it was so great, it inspired me to buy the Elna.
