"William Baker", probably the most famous maker of machines ever. Most of the great British makers of the 19th. century used "Baker" machines. Elegantly designed, yet simple. They have been around for more than one hundred years, yet really have never been beaten. These machines are still made by many accessory makers as there is no copyright on them. So why buy them from us? Easy to answer. Our quality is second to none, yet we try extremely hard to keep our prices at a sensible level. It is a funny thing to be remembered for, double bass machine heads. Specially when the designer and maker also made very fine instruments. Yet not many people remember "Baker" for his basses, just his machines. Life can be very perverse! The machine comes with a screw and washer which must be used to hold the cog in place.
