The information is collected from different web sources. Variations of Curta Type I Variations of Curta Type II I'm not sure about the different canisters... they have no direct relation to the serial numbers, so there is only an estimation possible. The list is a work in progress - so I would be glad to get your comments and suggestions  |

What do the numbers mean in the boxes? 968 known samples? but what is 901? wait I think I got it those are serial numbers. In the () is the serial number of the one with that feature closest to start or end number. Really cool, love the pics so its clear. VERY WELL DONE SIR> |

My 3198 has "Curta" apostrophe like your 2 var. but it has also numbers in the upper ring. If you need pics I coul try to take some good pictures.  Eliseo |

(...including variant "Additional numbering of the setting register at the collar") ... now with 25 differentiators for Curta Type 1 and still 18 for Curta Type 2 with corresponding pictures.  |
