Hi Steve, welcome to the group, I was going to tell you to take a photo every time you go to remove something or take something apart but Arnold just beat me to it. I'm a retired Locksmith, it was my last job before I decided to fully retire but now I'm thinking about going back to work again, I'm 71, almost 72 and this unloading and unpacking PODS from our move is just as bad as when I originally packed them. Anyway, as Arnold mentioned, taking photos is a really great way to be able to work on something, when I was working on a type of lock that I had never worked on before, I asked my mentor a few questions and then I studied the lock and started to shoot a pic every time I removed something. When I was a teenager, my dad told me to make a drawing of whatever it was that I was working on so I would have an easier time putting it back together again. That really helped me also but when I would work on a safe lock, I would end up taking many many photos every step of the way, I put everything in a nice neat order and then took a picture of it too, just so i knew what column it was in and how I could identify it., I also made notes as I went, so I'm sure you should be able to take it apart and put it back together again. If you can't get it back together, I'll be more than happy to buy it from you. 
There are also some really great repair guys on this forum and I'm sure they will be more than happy to chime in with some tips and such.
You will really like this forum, it has a very good group of members and for the most part are all extremely very nice, you might find a couple of grouches every once in a while but all in all, it is a great group to be associated with. They've really helped me out on more than one occasion. Again, welcome to the group and enjoy.
