Be proud of your dear oldie. I wonder if you are aware of how many of us quilters would buy her from you in a heartbeat.
I was very fortunate (after a long search) to find a beautiful Singer treadle machine at a garage sale about 6 months ago. It is a 1952 model in excelant condition.
I gave her a good clean and oil and hubby revarnished the wood for me. She sews like a dream with a much better stitch than any of my other 5 machines. I get so much joy from using her. I was very surprised when my daughter asked if it could be hers when I fall off the perch.
