Okay I removed the lock and took pictures before and after i cleaned it. There are manufacturer numbers on some parts. I have no idea how to remove the barrel from the stock. In the stock where the capbox lays there was pieces of wood that just fell out. I just added the photos to my Dropbox folder, new photos are at the bottom. If someone gives me a clue on how to remove the barrel, i'll do that as well.
