I've just purchased a small dial adder called the "Little Marvel Adder" and would like to know more about it. The instruction booklet calls it "the dollar adding machine". On the front it says "Manufactured by L. J. Leishman Co., Ogden, Utah" and "Copyright 1917 Patent pending". It is made from celluoid and has no carry mechanism, just celluoid dials that turn with a stylus and a riveted on metal "clicker" for each dial except the leftmost one. The result is read from windows on the back. Thanks John
