I just rediscovered a mechanical calculator that has been sitting in my garage for a decade or so. It's a Monroe Calculating Machine with no marking or label indicating a model or anything. black with a green face plate on top number keys are all black except for 3 rows of white 8 columns of keys roughly 6" wide, 9" long and 3" tall it's mounted in a small briefcase on the back of the machine is white lettering "Monroe Calculating Machine Company, New York, U.S.A" Can anyone tell me about this thing? Can anyone tell me how to find out more about this thing? Thank you kindly. Jim K
