I am the lucky owner of a list of Leica serial numbers, starting with the pre-production cameras in 1923 and up to 1965. I obtained it years ago in form of a bad photocopy. My apologies for that. However, it is still a very useful document which has shed light on many Leicas in the past and, I am sure, will do so in the future.
The list is 16 pages long, which cannot all be reproduced here at one time. The images need to be broken up into several separate listings. Enjoy!
