Have a look at the Restoration Procedure...
This adding machine  ( W*D*H = 6" * 7" * 5" ; 3 lbs )  is housed in a
die-cast aluminum case.  It is operated with a STYLUS,  stored in the
center of the lower body. By pulling down the appropriate BIG figures
the »PRECISE« performs ADDITION. With its  SMALL figures  SUBTRACTION
has to be used as  9-Complement  "Addition".  ( For  DETAILS  see the
BURROUGHS  INSTRUCTIONS ... )  Unusual is the MAGNIFIER, mounted over
the display unit for better reading.  To RESET the register, pull the
right LEVER.
