I've got two adding machines and an adding machine that I haven't seen on other webpages. I'd like to find out more about them. They are the Portable Adding Machine, the Little Marvel Adder, and the Plus Adding Machine made by Bell Punch and imported by S.W. Allen. Pictures and what I know so far are at: http://webpages.charter.net/pulley/Calculators.mht Thanks http://webpages.charter.net/pulley/Calculators.mht
