This is a vintage Singer buttonholer attachment set, complete with its original textured burgundy/maroon hard plastic case, instruction manual, feed cover plate, and multiple buttonhole template cams. The attachment features a sleek black enamel body with white Singer branding, a white top tension knob displaying the red 'S' logo, and visible width/stitch settings. Ideal for collectors of vintage sewing supplies or modern seamstresses using classic Singer sewing machines, this attachment creates precise, professional buttonholes. The original paper instruction booklet features classic vintage typography and graphics. The set appears to be in very good vintage condition with light surface wear consistent with age and occasional use. The case latches properly and holds all accessories neatly.
