This is a printed version of the manual for the Harris Streamlined Straight Stitch sewing machine.
The firm of W. J. Harris was not a sewing machine manufacturer but was originally a bicycle retialer. (Sewing machines were often sold in bicycle shops, particularly in the early days) over time they added more goods, mechanical and/or made from iron and steel, to their own branded range. As well as sewing machines these included baby's cots and cribs. In about 1960 they dropped the bycicles & increased the range of baby and child related goods they sold. By the mid 60s they dropped eveything else, including the sewing machines, and rebranded themselves as 'Mothercare'
