The Singer Model 27 and later model 127 were a series of lockstitch sewing machines produced by the Singer Manufacturing Company from the 1880s to the 1960s. (The 27 and the 127 were full-size versions of the Singer 28 and later model 128 which were three-quarter size). They were Singer's first sewing machines to make use of "vibrating shuttle" technology. Millions were produced. They are all steel and cast iron, and were built before the advent of planned obsolescence, and so they were designed to be repaired rather than replaced. Consequently many remain today, some in collections and others still in service. In company literature they were called "the woman's faithful friend the world over".
