antique Burroughs adding machine, olive drab industrial vintage mechanical calculator
Antique "portable" Burroughs manual adding machine in industrial olive drab, probably from the 1920s. This is in nice clean condition and works when we tested it, although it's faint on the printing and probably needs a new ribbon.
It measures about 14" long and 8 1/2" wide and is very heavy.
This does have wear to the decals and paint as shown.
