Leica 0 #123
Producción: 1923-1924. 31 ejemplares máximo con números de serie #100 a #130 (pero es muy posible que solo haya 26).
Leica 0 es la denominación que reciben las primeros ejemplares de Leica que se repartieron entre diversos usuarios para probar el producto antes de su comercialización.
Los siete primeros ejemplares tenían un obturador que no se volvia a cerrar, de modo que hacía falta una tapa para el objetivo que se usaba para rearmar el obturador. Esta tapa, unida al cuerpo por un cordel, se siguió proporcionando en los demás ejempalres que ya tenían un obturador que se cerraba automáticamente. The viewfinder (either folding or telescoping type) is located directly above the lens. (Image and data courtesy of Massimo Bertacchi

Reviews
Las cámaras de la serie 0 eran versiones mejoradas de la Handmuster y fueron usadas para probar el mercado. Estas oruebas This ‘test’ however should be taken with some salt as the users were mainly Leica dealers and employees. The Null-series of cameras have become extremely valuable collectors items. The range of allocated serial numbers runs from 101 to 130, but some experts claim that the range started with 100 and that 31 pieces have been made. Additional research however indicates that there are some holes in the number range and that at most 26 camera have been manufactured. The first batch of 20 cameras has the non-self-capping shutter and later cameras have the self-capping shutter that is used in the Leica I. Therefore there is a separation between the serial numbers: 100 - 122 (Leica 0 or Null-serie) and 123 -130 (Prototype of Leica I).
Below is the detailed list of cameras. The numbers 130 - 133 are presumably already Leica I models. Note that the first 45 Leica I cameras had been delivered to selected dealers for the Christmas 1924 sales. It is however not known when the cameras have been actually delivered to customers.
