A Rich History & Tradition of Excellence

Founded by Chartered Engineer William Mayberly Llewellin in 1883, Llewellin’s Machine Company Ltd first specialised in the manufacture of clocks and time recorders before becoming recognised as one of Britain’s most promising engineering firms.

During WW1, Llewellin’s could be found hard at work machining shell cases for the Ministry of Munitions. Our next chapter was written in 1927, a busy year involving the expansion of our floor space and incorporation, as we shifted our focus toward the manufacture of gears. Again, we played a vital role in the war effort during WW2, as we produced tens of thousands of gears for various ministries and purposes, from small aircraft gears and sighting equipment to wheels for tank landing crafts.
