I'm really new to the hobby, but it was kicked off for me by these old books I found in an antique store. I've tried to look up info on them, but it is fairly sparse. From what I can tell it has information spanning from 1915 - 1940? Can anybody shed a little more light (or history) on these books?


The locksmiths here can answer better than I, but the quick summary...
Lock manufacturers sometimes have a code stamped on the lock or the key. In most cases, the code is not the actual bitting of the lock (also known as direct bitting). The manufacturer has a table of codes that tells the actual bitting (cuts) of the lock.
Locksmiths starting keeping a listing of the codes and the direct bitting. Later, manufacturers started making the codes accessible to locksmiths who were distributors or dealers. Locksmiths started sharing the info, trying to create books of the data. Eventually an industry was created that collected the tables of codes from manufacturers and organized them into books for sale to locksmiths.
This is my understanding, and may be incorrect. But pretty sure I have the idea correctly.

Just when you finally think you have learned it all, that is when you learn that you don't know anything yet.
