Trade advertisement for a sewing machine manufactured by Singer and Wheeler & Wilson Sewing Machines. The text reads: 'The machines of Clas No 41 are especially useful for any proces requiring two or more parallel rows of fine lock-stitching; they are extensively employed in the manufacture of skirts, cloaks, suits, quilting etc'. Isaac Merritt Singer (1811-1875) designed the first practical lock-stitch sewing machine in Boston, Masachusetts, United States in 1850, totally revolutionising the textiles industry. In 1905 Singer acquired Wheeler and Wilson Manufacturing Company, but continued to manufacture some Wheeler and Wilson models.
