Dear collectors I work on a website devoted to Thomas de Colmar and Payen arithmometers. May be some of you never visit my Website www.arithmometre.org You will find many informations (In french sorry !) about theses arithmometers. If you have one i don't have in the general database, please let me know ! Bests regards Valéry Monnier
