Here is the lock totally disassembled:

The way I got the lock apart was by putting a really sharp and small chisel in the crack of the face plate and trying to gently work it off. It did come off with minimal damage. It sucked to have to do that, but I really wanted to see if I could fix it.
Here are all the levers lined up. If anyone can tell me why there are two gates I would be interested to know. I don't know a lot about these types of locks:

Here is a picture of the broken piece:

Here is what it would look like with all the gates lined up and the "stub" not broken off and what I had to deal with:


So I took an old key and cut a little rectangular piece out and started shaping it with files and my dremel:



Now I took the piece and carefully but firmly tapped it into place with a little hammer. Little hammer! Carefully!!!



I put the lock back together and finished the key. Now I am a happy camper. I really wish that I didn't have to have taken the lock apart, but it is what it is…

There is a little bit of damage to the seem around the faceplate. It isn't supposed to come off! I used a vice and cloth to squeeze the faceplate back on and then used the round end of a ball peen hammer to "squish" the posts back into place. The whole lock is brass so it is pretty soft metal. You can tell it has come off if you look closely, but I am surprised that it looks as good as it does. Almost as surprised as I am that I got the thing fixed!
If anyone would like to add something or correct any of the terms I used, please do so! This was a learning experience for me and I am very proud of the fact that I got it back together and that it is now a "lock" again and not just a broken dream…
Back when I first started picking locks I never would have thought that I would be doing these sorts of things. I owe so much to this site and the people who have taken time to show their work. I hope that someone learned something from this. I wish that I would have taken more pictures or even videos, but perhaps next time I mess something up.
