Unknown Lathe No. 79
A Wolf-Jahn Model DD
Unknown Lathes Home Page

Resident in Germany, this bench precision lathe does have a German/Lorch look about it - but has now been identified as a Wolf-Jahn Model DD. However, the very large and sophisticated countershaft drive unit (which looks to be contemporary with the lathe) has not been seen before by the writer and is of the "stepless" type with a constant, infinitely-variable speed range with start, stop and reverse available through the lever protruding horizontally from the turret. The innards may contain a swash-plate or friction cone drive, a small version of the latter type, suitable for a watchmaker's lathe, being made in the GDR (communist East Germany) during the 1950s.
