Took off my old doorknob...here we are

Title explains it all. My latch bolt was stuck in the strike plate while I was inside the room. I was able to take everything off and this is the result. My wife and I bought this 1860 home and have been working on the house. We realized this door locked which was nice, but it got stuck multiple times so I am trying to clean it up. When I took the plate off the spring on top popped off with the other two pieces to the left and right of it. I am trying to reassemble everything while also getting the latch bolt unstuck.
