It is a Gritzner-Kayser made machine sold as the Domestic 691, probably the least common of the variants of this machine. These were make in 1956-1958. There are Kenmore, White, Domestic, Pfaff and Gritzner-Kayser labelled variants that I am aware of. There is at least one more version that takes a slightly different cam set that was make in 1959-60 but I've only seen it as a White and Gritzner
