Statistics |
 |
| Nearly 300 machines listed! Yes! This is the result of a long work of research and partnership. Thank you again to museums around the world and private collectors who have helped me in this crusade! There is still some way to do, hypotheses to be tested, but the puzzle is set up, slowly .... / VM |

| * Production of T1850 A could be much less .It is possible that a centain of numbers was assigned in the workshop register, but after all, few of them was used (built)... This hypothesis is evaluated. | ||||||
