Manufactured in Hannover, Germany, nothing is known of this backgeared and screwcutting lathe, nor of its maker - though I understand that iHaedge & Richter was a dealer and distributor of machine tools, not a manfacturer
Please see: https://www.zvab.com/Werkzeuge-Gro%C3%9Fer-Produktkatalog-Firma-Haedge-Richter/21943586662/bd. With a double B-section, V-belt drive to its plain-bearing headstock it would have most likely have been current from around 1935 onwards - as modern-type V-belts only came into use in 1930. Production by many Western makers of this rather 'vintage' type of light-duty repair-shop lathe extended until the early 1950s, though then virtually had all-geared headstocks. Other pointers to its age include a simple countershaft unit hinged to the back of the bed, two cast-iron support plinths joined by a simple sheet-metal chip tray and a bed of a type beginning to favoured at the time; this being of an asymmetrical pattern with a wide, shallow-angle way at the front to absorb wear and a more steeply-angled back to take thrust. For additional stability, the way at the rear of the bed appears, on this lathe, to be formed with narrow rectangular guides.
Judging by its specification, this would have been a lower-cost model with screwcutting by a simple gearbox with perhaps three rates of feed and screwcutting for each setting of the changewheels. Note the typical German-for-the-time tumble-reverse lever with three rectangular engagement slots.
Do you have a machine tool badged as a Haedge & Richter - or any sales literature? If so the writer would be very interested to hear from you.
