"Sheppard" machines, named after "Godfrey Sheppard". These are a lovely designed machine that work and look really well. These were designed about ten years ago and have always been a good seller. The machines come with a screw and washer, which must be used to hold the cog in place. They suit all styles of instruments and have been used by many of the Worlds great makers, but mainly they have been going to German makers and dealers. We have even sent several sets of these cogs to dealers and repairers in Africa and South America, and in early 2001, we actually sold a set to a Russian maker, thus breaking new ground.
