What was in the stone box with the Gold Plates?

The prophet Joseph Smith, in his testimony, said that the Plates, Urim, and Thummim were in the hill with ‘other things’, including a breastplate. I can probably find out what those ‘other things’ were in the end of Moroni, when he buries the Plates. At the end of Moroni, however, it just says, ‘I hid up the plates unto the Lord’. In Mormon chapter 6, I find the words, ‘… hid up in the hill Cumorah all the records which had been entrusted to me by the hand of the Lord, save it were these few plates which I gave unto my son Moroni.’ So, Moroni only burried the plates that he wrote in, and Moroni hid everything else. But what was in there? I found Doctrine and Covenants 17:1, which says, ‘Behold, I say unto you, that you must rely upon my word, which if you do with full purpose of heart, you shall have a view of the plates, and also of the breastplate, the sword of Laban, the Urim and Thummim, which were given to the brother of Jared upon the mount, when he talked with the Lord face to face, and the miraculous directors which were given to Lehi while in the wilderness, on the borders of the Red Sea.’ That tells me that the ‘other things’ were: Laban’s sword, the brother of Jared’s breastplate, and the Liahona.
