ANTIQUE VINTAGE CARL WALTHER GERMANY PINWHEEL CALCULATOR / ADDING MACHINE AN OLD SMALL BUT HEAVY PINWHEEL MECHANICAL CALCULATOR / ADDING MACHINE BY CARL WALTHER, GERMANY. BACK PLATE PORTRAYS A MODEL NUMBER (RMZ) AND A SERIAL NUMBER (15594). CIRCA 1930'S.STILL IN FAIR VINTAGE CONDITION. ALL LETTERING AND NUMBERS ARE READABLE, AND THE 4 RUBBER FOOTINGS HAVE RETAINED THEIR SHAPE. THE MACHINE IS NOT FUNCTIONING PERFECTLY, AS THE HAND CRANK ON THE LEFT HAND SIDE (I PRESUME IT IS THE "COUNTER") DOES NOT CLEAR BACK TO ZERO UNLESS YOU PULL IT OUT WHILE CRANKING - PERHAPS THAT IS HOW IT IS SUPPOSED TO FUNCTION. ALSO, THE RETURN CARRIAGE APPEARS TO HAVE MORE THAN ONE POSITION, BUT ONLY WORKS WHEN COLUMN 6 LOCATED ON THE RIGHT HAND SIDE OF THE CARRIAGE RETURN LINES UP VERTICALLY TO COLUMN 1 OF THE UPPER BODY SECTION. THOUGH THERE IS A "SUBTRACT" SYMBOL (-) LOCATED AT THE UPPER LEFT, I WAS ONLY ABLE TO COMPLETE SUBTRACTION TASKS BY TURNING THE CRANK COUNTER CLOCKWISE. AGAIN, MAYBE THIS IS HOW IT IS DESIGNED (AS THE "COUNTER" DOES SUBTRACT WHEN THE SYMBOL IS ACTIVATED). ONE OF THE HAND CRANK PLASTIC HANDLES IS MISSING, TOO. INITIALS "R.P." ARE ETCHED ONTO BACK SIDE (LOWER LEFT).I RECALL MY FATHER TAKING IT APART WHEN I WAS A CHILD TO CLEAN AND REPAIR IT. HAVING NOT INHERITED OR LEARNED HIS MECHANICAL SKILLS, I DECIDED NOT TO ATTEMPT THAT FEAT. read more
