Fischer were lathe manufacturers, based in the German town of Freital in Saxonia. Inscribed on one of the older machine illustrated below - probably from the early 1920s - is the following legend:
Fischer & Co. Komm Ges Speczialfabric fur Drehbanke Freital i. Sa. Other pre-WW2 machines have been found with: Fischer Spezialfarbik für Drehmaschinen GmbH, Freital in Sachsen. After WW2, the town of Sachsen became part of the GDR (German Democratic Republic, the communist-controlled East Germany) and company's name was changed to VEB, a German abbreviation for Volkseigener Betrieb, the People's Enterprise, and became part of the WMW (Machine Tool Union) of the GDR.
However, in common with many other manufactures who fled to the West,  the Fischer brand was also to be produced in West Germany, its name being joined with that of EWK (Eisenwerke Karlsruhe) 
Shown below in a set of photographs is a green-painted Type KBS Fischer lathe with a swing over the ways of approximately 15 inches and a distance between centers of 40 inches. The V-belt driven headstock incorporated a clutch with the six spindle-speeds selected by two levers, one on the front of the headstock and the other on top - the label on the headstock reading:
Scalten-nur beim Auslant
Umdr. der Arbeit ssp. pr. 1 min.
Hebel Mit Vorgelege ohne Vorgelege
Middle  26 151
Bottom 47 273
Top      84 490
A basic translation would read: Let the lathe stop before changing gear and Lever with reduction gear and without reduction gears  Thus, the spindle-speed range ran from: 26, 47 and 84 r.p.m. in backgear and: 151, 273 and 490 r.p.m. in direct drive.
A conventional tumble-reverse mechanism was incorporated inside the headstock casting and below the left-hand end of the headstock spindle; it drove down to a screwcutting gearbox with outputs to a leadscrew and a powershaft for sliding and surfacing feeds.
