Although one of the two examples of this unknown lathe is branded as a "Lerbs", this was actually  the supplier, a ships' chandler based in Bremenan and the lathe is known to have spent some of its life, from 1961 to 2001, on the Pilot Ship "Kapitän Hilgendorf". 
Looking to have been designed in the early 1930s (though probably of much later manufacture) this conventional backgeared and screwcutting lathe is German in origin. Fitted to a neat, underdrive stand it features larger-than-usual slide-rest micrometer dials and massive tumble-reverse gears.
