Heh...you just sent me on a journey through some of my hellboxen since I didn't remember the name of that particular machine and I had to dig out the book where it's in (Buchungsmaschinen, GMD Report No. 162, by Werner Lange). It has lots of pictures and drawings about both adding machines and bookkeeping/facturing typewriters (Wahl actuator, Burroughs-Moon-Hopkins,...) However it looks like I mixed up some stuff:

The typebox printing element depicted in the book is described as belonging to a Burroughs Typing Sensimatic - an advertisement can be seen under ebay auction number 260181621699, but this shows a typewriter keyboard in front of the adding machine part.

The keyboard with dual legends depicted in the book however (which I wrongly associated with the typebox) belongs to a German Zeiss-Ikon adder from 1958, no further classification given. The printing mechanism of this machine is described to consist of three disks or typewheels able to print a set of 42 characters.
