No, it�s not the same kind of marking. The image posted just above is a Waffenamt/Acceptance stamp which was applied to new manufacture items coming from a factory. The example pictured is a variant that gun collectors would call the "droop wing" version with down swept feathers (a topic all by itself).
For the enlisted cavalry man�s saber below it�s an armory rework mark - identifying the armory where the work was done. The small marking above with the red arrow is a previously existing Imperial era marking (inverted).
When the saber was overhauled any Imperial unit markings were removed. A new walnut grip installed. And the scabbard was heavily blued. The saber itself is a scaled down version of one that was carried as far back as the Napoleonic Wars. FP
