Background

Found this on eBay.  It appears to be able to print a 9mm wide paper strip in conjunction with Morse Code.
Most likley German (because of the Morse characters used and a couple of screws have 3-0.5mm threads.
The connectors on the end of the wire look like very early Dual Banana Plugs (3/4" c-c).

WHAT IS THIS?  Let Me Know
Tom French may have come up with the answer:
"It's an early prototype of the Dymo label printer."

Operation

White Lever

As the lever with the white knob is cycled over it's full travel the type wheel is rotated more and more.
After 7 cycles it can go no further.
This may be related to the numbers shown on the led (see Fig 3 above)
Each cycle of the lever makes and then breaks a circuit.  But the speed of operation is way too slow for sending Morse, so maybe it's a paper tape preparation device and there's another machine that reads the paper tape.  The tape has only human readable characters.

It's possible to move the typewheel one position since you can feel the ratched click.

Black Lever

When the lever with the black knob is operated it moves the paper tape for a print operation and lets the type wheel unwind.
While working the levers the paper tape access door needs to be closed with the takeup reel pressed all the way inside.  When in this position the takeup reel is incremented with each actuation of the black lever.

Battery Compartment (Fig 1)

There are two battery positions, one for a 30mm flat lead spacing and the other for a 40mm flat lead spacing.  Since a AA battery is about 14mm diameter those batteries are probably 4.5 Volts and 3 Volts respectivily.  This type of battery was common in "Pocket Flashlights" a current one is the MN1203 4.5 Volt battery.
