About the "swastika" pattern in the fabric. This symbol is older then dirt and goes much farther back in history than WWII, and may not be what we see at first glance, and if it is then it is a piece of history, not to be shocked by it, but learned about and history passed on so as not to forget.
As for the quilt, It is an interesting pattern I have never seen before. I think you may want to look into it further by a conservator.
