Are you going to turn her into a treadle?
I have an industrial machine 241 - the bottom was full of big oil beads when I got her - nothing moved. All the oil tubes were very hard. I got her moving but the tension spring is wrong. I haven't got her sewing yet. If she didn't have such a good motor she would be a good one on a treadle. She turns real smooth. Someone had her in their house for upholstery then she set for years. Her table is like new. I need to get DH to put her head back on so I can work on her - she is pretty heavy.
