"William Tarr", a Manchester maker of the 19th. century. To me one of the most diverse of the English makers, with more than four hundred double basses to his name and hundreds more made by many makers who worked for him. Yet with all these double basses he also made violins, violas, cellos and these machine heads. At least these are a close copy of what he draw up as a design. These, like the "Bakers" are a beautiful example of the classic English design, and just suit any instrument. Though they come with a screw and washer, they can be fitted without going through the peg box. The fitting of the worm and thumb screw will hold the cog in place. Very low gearing which gives very fine tuning.
