It appears that the stitch length adjustment lever (the big vertical silver thing on the main body(pillar)) has the ability to be placed all the way to the top and the machine would stitch in reverse (makes ending seams more secure) That feature was for the most part not available until about 1915-1920 for domestic machines.
One of the really nice things about German machines of this era is that they maintained the old school method of having the needle bar "bob" once during each cycle(like a seamstress of old tugging each stitch tight) but also were early adopters of the reversible drive engineering. Makes them some of the best machines EVER to sew with. (Yes, they do make a better stitch than a modern machine)
