I rescued two antique Singer sewing macines from a basement in Bristol, Virginia this past weekend that were going to be given away to the man that was hired to clean out what was left in the house. A treadle model 31 that was manufactured in 1901 by the Singer Manufacturing Co. and the other one is the same model you have jumpin' judy which I don't know what that model is but the needle plate says the manufacturing date was 1910.
