Decided to jump in here. Old Singer treadle machine sitting in my home for many years and just opened it up to dust inside and saw how pretty it is. In the process of looking for a belt found out that it was made in 1910. Ordered the belt and some new needles and will see if it still works as soon as they come. Attaching a picture. Could not find a model number anywhere. It was one of 25000 allotted Nov 10 1910 and made in Eliabethport factory in Elizabeth NJ.
