I really need help on my "new singer treadle" It is a wood cabinet It has two plain drawers on each side-no carvings.. The head is perhaps older than the cabinet. It has Sphynx decals, a drop feed, a round bobbin There is no date or any numbers on it. The manuel that was given is for a class 15. She told me she bought it at an estate sale and knows nothing about it I looked at this for over a month before I went back and bought it. Paid way to much for it I am sure. The head looks like the 1904 model with the same decals . The stand is in excellent condition There were no feet etc with it. Can anyone help? Please. Marvel
