Just thought I would try my luck here; I am trying to track down a copy (.pdf or otherwise) of the following articles as John L. Sorenson references them in his book, Mormon's Codex: An Ancient American Book (2013) on the topic of pre-Classical Mesoamerican metallurgy and its relationship to the material culture of the Book of Mormon. If anyone has any of them, feel free to forward them to my email address (irishlds87atgmaildotcom)
