When I look at those three photos like that, I DO think they are the same rifle. I say that based on the grain streaks running out of the checkering on the forearm. They are too similar to be different pieces of wood. The poor resolution and lighting of the middle photo is a problem but I think they are all the same. The bottom and top are more easily put together.
