The offering featured here is a 1940's era buttonhole worker attachment, the "Famous" Buttonhole Worker, from the Lenox Manufacturing Company of Catasauqua, PA. The booklet to this piece is not dated, but it looks like the other ones from this era so just guessing at the date of it. It has the screw and hardware necessary to install on your import machine. This "Model CC is made for use on Import sewing machines" as stated on the end of the box. It is free of rust and wear and is without damage. The original box is soiled but still strudy and intact. It is in very good condition for the given age. If you have any questions about this item, feel free to write us. We'll get back to you asap with an answer. Thanks for looking in today!
